Doing a presentation of 1 min took me a lot to learn it and then I messed it up. This guy spoke for more than 40min without lagging. Respect!

Probably the best tutorial on functions, cleared all my doubts.

I was devastated on an online course. The material they provided explains exactly what you do in this video. I just could not comprehend it without someone show me exactly what you doing here. Thanks you for making this videos available to learn. You are a good teacher.

I love it how our favorite Ninja explains things not only to impress the viewer but to actually make the concepts in question available for understanding. Weird notion, right? Any tutorial is supposed to explain things after all. But you'd be surprised how the vast majority of them are uploaded for ANY other reason but break down their topics in a clear and concise manner. Kudos to Shaun for putting these out for free!

mate you're better than the 3 years i wasted on my bachelor's

my 3 months of trying to understand javascript have been summarized in 43 minutes and i have actually understood smth for the first time ! Thank you, Man !

Just like all your videos, I love that you write out the functions several ways, function() vs arrow function so that when we have to look up our own issues, we aren't completely lost when we don't find a consistent answer. You are really helping to show standards. Much appreciated.

i've watched many tutorials and read many articles, but you explained it with great detail and with good examples. Thank you

My dumbass literally cried cos I finally get it.. after watching hundreds of other tutorials, this video was a eureka moment T_T ..My ADD finally get how it works, God bless dude T_T

You have a gift to teach. Your courses have very good content but you can also teach and explain very well. I'll definitely be buying your course.

Hi Shaun, I was a KZfaq tutorial nomad until I found your channel. Man oh, man! You have such an awesome teaching style that makes everything easily graspable regardless of any toughness level. As soon as I finish your modern JavaScript Tutorial, I am going to buy your React course on Udemy. I wish I had found you earlier. Thanks for everything you do mate! Much appreciated!

I don't know about anyone else, but for me I need to see what all this code is actually used for in a real example building something; project based learning (not logging things to the console). Otherwise, I can't absorb it because I can't associate any meaning to what is being shown. Showing how functions work without context, for me, is similar to just giving a long list of random numbers to remember; don't know what its for or how to use it.

Not even halfway through and from this tutorial alone, I understand functions better than most of the other videos + codeacademy! Great tutorial

I think the main thing that this tutorial is missing is having the viewers actually participate, like instead of just learning things, putting those things to use as we build something. Besides that, this is very helpful. Thank you!

I purchased a web development course in Udemy which turned out to be outdated, I then purchased another one which was sold as "2020", this one was not using the old ways to declare functions and skimmed through functions, leaving me in doubt and confused. I stumbled across this video in my search to clarify functions and I am glad to say that Net Ninja has cleared my doubts and I now feel more confident using functions. Thank you!

thhhhhaaaankkk you! I don't know why my head couldn't grasp functions but I needed just a simple tutorial like this

only an expert can explain fundamentals this simple, thanks A lot !

Your real life example of forEach() method with HTML is a brilliant way to explain its purpose. Thank you!

At around 15 minutes you start explaining local variables. You absolutely nailed it. I am currently working a treehouse techdegree and you have proven a valuable outside resource.

Never had such a clear explanation with respect to functions and passing of arguments or parameters.

Thanks to you I was able to pass my js entrance exam thank you so much 😭

Your teaching style is so clear and easy to follow. Thanks for letting us preview before buying. :) With so many JavaScript Udemy courses, this really helps me decide!

it reallly helped me understand the topic more when you mention explicit terminologies. others just mention it as 'other way'. thank you for this!

You are the best teacher on KZfaq who can explain core concepts clearly. Huge respect

I've watched a lot of tutorials about functions but I'm difficult to understand it, until i saw this video. I'm very comfortable to use function now. This is so helpful. Thanks bro!!

You really explained functions well. I'm doing Jonas Schmedtmann's Javascript course on Udemy and, although he's a good teacher, his section on functions left me a little bit dispirited. Your 'earthly' explanation of functions was excellent. I think I'm going to do both yours and Jonas' Javascript courses together, you compliment each others' efforts. Just got to wait for a bargain sale day/week at Udemy and I'll be signed up for your course. Thanks again for your efforts, you're a natural; and there are fewer higher callings than teaching.

I have watched many tutorials, yours is the only one that make sense to absolute beginner. Other's are too lazy to explain basic concept, and I like you keep doing different scenario to clear our questions, such as "what if I do this...", "what if I want to do that?" Those are great because those are the questions that never got answer in other tutorials for beginners. Thank you so much and keep up this style of tutorial!!!!

The way you explain functions is soo good! Thank you very much!

@TheNetNinja I love you tutorials. I'm a beginner in the programming world. And I'm starting with JavaScript. I've been following your videos now for awhile. It's really been helpful. Thanks a lot.

The best channel to learn javascript. I learnt so much in 5 weeks of watching your videos!

This is the best video I've ever saw on javascript functions. Couldn't find such a good source even in my native language.

I haven't seen any tutorial so far which covers functions in great details as him. Well done 👍

You have a great voice for this stuff. You don't sound sleepy like most of the other popular youtube webdev gurus.

I was stressing over functions for DAYS until I hunted down this video. THANK U

I don't even want to go to a college to learn to code. The best ever JS lesson on the Internet!!!

I am IT student on Level5, but you teach to me a lot. It is very clear. Thank You. I follow you.

I've watched dozens of videos on functions & this one is succinctly put....

"We know that methods are functions too we have also seen that we can pass arguments into functions and methods when we invoke them and we can use those values/arguments inside the functions and so for those arguments we have been passing in have been things like strings numbers but we can also pass in function as an arguments and when we do this the function we pass is called a call back function" my mind exploded a million times when he said that

By watching how you explained FUNCTIONS thoroughly (not boring and not too complicated) and how callback works, I'm a follower! I've subscribed and will watch most of your videos now! Thank you! You made learning easy!

Man you nailed it . I saw too many tutorials and article but havent got clarity about terms. Your videos cleared all the points in one shot . May go bless you . Thank you!

i actually got a JS course on udemy but was unable to fully understand the concept of functions properly so i came to youtube to get more claification and that is exactly what i got from this tutorial. My only issue is you were speaking to fast but that's where subtitles come in handy.

I paid for someones udemy js course and I had to come here to understand functions better. Thank you so much!

Thanks for this! I should absolutely buy your full course

I am Competitive Programmer ... getting shortlisted for interviews but facing rejections bcz of less projects as compared to others ... this playlist helping a lot to boost resume in short time

I have PHP background av always been lazy to switch to JS. You are the best tutor av ever seen online. Thank you.

this is the best explanation of function that ive seen in entire life, thank you!

is almost 2023 and im still watching this video,,,, great stuff man

You are a LEGEND bro, how can you find these easiest way to explain things? Very IMPRESSIVE!

🎯 Key points for quick navigation: Functions are blocks of reusable code. Functions allow for code reusability. Parameters pass values into functions. Error function example Callback function definition Using for each Made with HARPA AI

Absolutely amazing course. Very well explained..I recommend this to anyone who is starting off with Javascript . I am also a beginner and this course has really helped me a lot.

I am grateful for being able to use this kind of amazing resource. Probably this is one of the best one on functions. Thank you for making this. God bless all.

Probably the best vid you will find in youtube on function and also better than most of the paid courses !

this is the best explanation that i found so far

Best I ever watch regarding function in JS.

Man! You are more than AWESOME! I am a big fan of Your tutorials and in my opinion this one is the most understandable material about modern js I've seen since now, comparing even with paid ones! Thanks for what You are doing for us!

i just love love love the way you teach, so clear, so easy to understand..thank you so much, God bless you for sure, this is the best tutorials on the planet

Words fail me to explain how you have helped me. You are really the best

You are the second person today to tell me that functions are fun

Thanks , I follow you from Syria ... continue!

You are the best teacher.

The best video I've Came across so far, Filled a lot of holes in my brain. Thanks!

Thank you, THANK YOU! I've been struggling to wrap my mind around the anatomy and setup of functions and this really clarified it for me!

all right then gang we can see that Shaun is clear and concise as always. Beginners will find this to be another ruby from him

this is the tutorial for beginners with 10 years of coding experience :D

Dear Ninja, you are perfect teacher. I am a beginner. You said in the video that arrow functions have some disadvantages. I found a problem and i could not solve it. const identity= { name : "Net", surname : "Ninja", writename () { return this.name+" "+ this.surname}, writename2 : () => { return this.name+" "+ this.surname} } writename() returns "Net Ninja", however, writename2() returns "undefined undefined". So, what is the reason why arrow function does not return names correctly? edit : I found the answer in "Modern JavaScript Tutorial #5"

I think functions are the hardest concept in any programming language.

Thanks for all your tutorial. It really really helpful to me... You make me understand Every day in web development... I love you so much.. .. Note .. you are the best to me.....

Best way of teaching,clear my doubts about function.thanks a million.

I left programming course at college because of this Dude, and I don't regret my decision anymore😌.

The best tutorial on functions.

So far this is the hardest thing for me to grasp. I need to rewatch this one for sure.

//Arrow function const billings = (prdct, tx) => { let totalamount = 0;//local variable implicit with local scope for (let i = 0; i < prdct.length; i++) { totalamount += prdct[i] + prdct[i] * tx / 100; } return totalamount;//it takes value from totalamount local variable and pass it function caller }; console.log(`Your total amount is: `,billings([10,52,63],18));

Wow! I am amazed with all of your videos. You've helped me to solidify so many concepts, especially when using Node.js. I'm watching these as a refresher and I'm highly impressed with all your videos. I'm excited to learn React from you

who else wants shaun to extends this course...

I really love you dude

If I could jump out of the screen and hug you I would haha. This topic has been difficult for me to understand but the way you explain it is so clear and easy to process. Thank you so much

You're so talented at teaching. Keep creating incredible videos!

never clicked so fast on an javascript tutorial video xD

22:09 I never thought a tutorial video could make me laugh so hard, the "pun intended" killed me lmao

Thank you for the best content Bro.🙏 love frome Tanzania 🇹🇿

Best Code Teacher 💪❤️

Great stuff! One of the most helpful channels i have found while learning JS

However I love your teaching style I think that example of callback functions is very hard to get. You could explain it a lot easier IMHO but overall your stuff is great.

By far the best explanation of functions I have seen this makes so much more sense now.. Will be buying one of your udemy courses. Love the content thank you so much.

just a couple videos, and I had to buy this course. the way u explained stuff just made it so clear and easy to absorb. Thank you

Doing another online course but I either forgot functions or they didn't cover it as well as this. This was great.

You are awesome. You are a teacher. I wish i came across you earlier.

Best JavaScript Tutorial, I bought the full course and it is excellent ! , Arrigato Net Ninja San !

That was just awesome. You are showing how to exaplain complex stuff in simple way. Keep your work man! Thanks a lot! :)

Great video could you please make a vid on algorithms

You can simplify the arrow function in 26:43 even more: const bill = (products, tax, total = 0) => { for (let i = 0; i< products.length; i++) { total += products[i] + products[i] * tax; } return total; }

By the way, maybe u do not know, but what you did/taugth beginning at 31:46 makes A HUGE DIFFERENCE! I´ve been studying programming for 3 months and struggling a lot with CB and HOF. Apologies for any english mistakes, i´m from Brazil and need to learn more! haha

oh so glad i found this, easily best js functions explanation seen so far on youtube thank you sir, will follow all your other content

Exceptional clarity.

Thank you Shaun...bringing in real usage like this html ul made me understand this callBackFn clearly...this was a nightmare for me earlier...surely going ahead with your Udemy course..thanks again

One of the best videos on this topic I've ever seen. Thank you so much! Bought your Udemy course already :)

Thank you so much for these videos. I love your teaching style, very thorough and effective. Thank you!!!!!!!

God bless you my man, you are doing a great job, you have removed lots of confusion of mine.

I’m 1 min and its making all sense now!
