This 5 minute video made more sense than my hour long online modules. Thank you!

This is a simple easy to understand tutorial on JS functions. I caught myself wondering how an array of objects with firstName and lastName arguments can be updated automatically. It is a natural building step. Thank you for putting this video and so many others out there for others to grow from.

I've watched tons of videos on function but this short clip summarizes everything. Thank you Sir Mosh

I am Brazilian and suffer from the scarcity of this type of content. your video helped me a lot. Thanks!

You are the best. I started to feel like coding wasn't for me until I found your videos. Thank you so much, Mosh!

Thank you Mosh! Very simple and straight forward. I am currently a Junior Web Developer and working through a boot camp for Full Stack. This was short but helpful and to the point, excellent material.

This is the cleanest/purest/easiest explanation I've watched about functions. I learned it. Thank you!

I would also like to share that you can add a default parameter. For example : function greet ( name= 'Valued Customer').... so that when you don't add any value to the argument, it comes out as: Hello Valued Customer . I hope that helps! P.S Whatever argument you would add later would override the default parameter.

Thanks a lot. You made it very simple

thanks again mosh. you did a much better job of explaining this to me. I was stuck in Codecademy :p

You are an inspiration. Every time I'm stuck, I watch your videos and you make things very easy!

You've just cleared up exactly why someone should use parametres instead of variables - somethign I've been trying to find a clear explaiantion for - for ages!

I completely understood that how to operate function. Thank you for lesson.

You explain everything so clear! Thank you loving the videos

I am learning JavaScript and was having trouble understanding functions. Your explanation was extremely helpful with my understanding. Thank you!

This is EXCELLENT. Really awesome job of concisely dealing with the composition and components of a function.

Your teaching style is so great Thank for the video

argument is the supply of the parameter while parameter is the name of the input when function is declared. Superb!

JazakuMullaha Khaira!!..Aameen!!..

I am relieved of Arguments and Parameters in JS Now, thanks!

So let me see if I've got this straight... A parameter - a unique term typed inside the "function( )" parentheses becomes a variable that is only valid when used within that function itself. also @ 3:02 - 'most programmers don't know the difference between a parameter and an argument'. This is very helpful. I've been studying JS for a month or so, and I'm trying desperately to find the "aha" moment of calling functions and how they relate to creating actions at specific moments.

I'm learning JS for the first time. You explained this so succinctly, well done. Thank you.

You made it so simple to understand. Big thanks from Australia

thank you so much sir! y'all JavaScript videos are so much knowledge and easily to understand for beginners.... i appreciate it!

Thanks from a very happy lady looking for quality coding tutorials to supplement her learning! Legend!

You're a legend my dude!

Professors talk, teachers teach. You are a teacher. Thank you!

Thank you again for making programming understandable ! I can't count how many times i have spent hours on simple problems and found the answer on this channel

Explained it so well in just 5 min. Lemme tell, this concept was so confusing for me and your 5 min video made it all clear. Subscribed 👍

Are computer functions the same concept with math functions, relating parameter( input) and argument( output)?

JazakAllah!!.Aameen!!..

I get it that you want to show people how core JS works, but why not briefly show that and then move on to how we should be writing it today? I just think that modern JS (ES6+) should be taught up front now instead of people having to search for those lessons specifically. Just my opinion. Please keep the great content coming!

Alhamdilillah!!..Aameen!!..

This 5 minutes video makes a lot of sense,I love all your KZfaq tutorials I attended ❤️❤️

Great! Thank you. I pray all your videos are this good

This helped me understand parameters more, thanks boss

MashAllah!!..Aameen!!..

In ES6 you can also add parameter defaults.

formal Parameter and actual Argument

Thank you for this short and great explanation!

Can i please know how you setup your VS code with the javascript and the output to

short ,concise and self explanatory thank you

Thank you. This video really made my day.

subscribed....Thank you for taking the time to explain this without leaving out any basic details. So many times people who understand things explain them to people who don't as if they have the same experience level or knowledge.

Mosh is the BEST, Thank you

Exactly what I was looking for. Thanks!

Thank you for these, very well elaborated. God bless you

This was really straightforward and simple. Thank you

great videos for a new JS developer! thank you

crystal clear explanation, best I've seen. Thank you!

Thanks a lot! I understood functions only thanks of this lesson

hello Mr mosh I want you to explain callback function plz I am so confused with it

Oh my... It was very helpful. Now it more sense. Thank you!

for a beginner whats the effecient advice to get more advanced in programming

Great channel, great tutorial. In-depth, straight and clear!! Appreciated ❤️

Lol i was trying soo hard to learn this for hours ...But sir u did it in just 5 minutes..🙂 thank u sir u are a fgging goat..

thankyou so much.I was so confused about what are parameters and i finally got it

An excellent lesson, short and easy to understand.

🙃🙃🙃I feel relax after getting the point. This was one of the most confusing one which you solved for me.

Thanks 🙏 you sir I really appreciate it finally my doubts is cleared thank u god bless u sir

Thank you =D

Love u man🤝

Great Video bro!

Wow amazing

question!: but how does the console know that the argument 'John' is a (name). Do you not need to declare anything prior to logging it onto the console??? is the parameter arbitrary? can you replace it with e.g. greet(pizza)??

thank you for your help.

Great video thank you brotha!.

nice teaching,thank u

Hello, purchased your JavaScript course👍😊

This cleared my mind so well, cheers man !!!

Thank you a lot. it is helped me to understand the javascript function.

Thanks! This made sense. I’d love to see something a little more complex with what functions can provide. Thanks again!

why do we need the + sign for. a coma will do the trick

Wow. Just wow. This is a like and a sub, I just started learning programming and I feel like I’ll come here often.

This makes way more sense now

Thank you for sharing.

thank you , very much appreciated

great explained!

mosh ur best fr ı hope u will hit 3m subs

Glad to found this! Quite helpful and straightforward :)

this explanation is so simple

Thank you sir!

you should do longer videos where you explain certain programming languages!

Thank you bro.

Thank you for lesson. How can I download visual studio code theme like yours?

SubhanAllah!!..Aameen!!..

Boom. You nailed it. Thanks Mosh

Are there any other examples?

Great video - super helpful!! Thank you for sharing.

yooo man, thanks a lot

Thank you!

Why don't you end a function declaration with a semicolon?

Is there any way to extract variables from a function.

Thank you so much

You earned yourself a new subscriber Mosh! Good Job!! Wonder if the coder have to input as many arguments as the number of parameters? thank you :)

Thanks a lot. it was very meaningful video

well done -

Hello Mr.Mosh, I have been playing around with the Google Maps JS APIs and I tried what you just showed in the video and I didn't see anything appear in the console. For some background, I have separated the code into three different files, location.html, location.js & location.css. Is it that I should keep all the code in one file or is it something else?

Why is it so simple and so difficult in the same time 🤯🤯

What is the purpose of the space? in the console log between last name and name?
