If companies or developers stopped releasing new JavaScript libraries or frameworks every nanosecond, maybe I wouldn't hate it.

I know PHP, I know Rust, I know SQL, I know Shell-script, I even once knew C and C++, but I have never managed to get comfortable with Javascript. I don't think I ever will. It never ceases to confuse me.

Null actually means null pointer. Values that contain objects are actually pointers to the object rather than containing the object themself, and null is pointer to nothing. Which is why typeof null is 'object'.

Thanks for your amazing content Mosh. You videos are not only very engaging and useful, but also very therapeutic and refreshing 😊

I'm deeply learning html and css right now next it's javascript, I want to be frontend developer

I just started a full stack JS job w/ data analysis job duties too. Seeing this video has made my heart skip a beat.

meanwhile im 46yo,self taught and still learning JS >HTML>CSS>React with vite for the last one year, im having fun learning JS because i want to be front end dev for my freelance journey

hello sir, its great to see you again

Great video Mosh, the video was great! You are the best programming professor in the world!!!

JavaScript is weird, but somehow I love it so much.

Okay where does 2:17 come from?? It seems hilarious

JavaScript is the chaotic language something like the internet deserves to represent it.

I decided to take JavaScript seriously because of Dash's clientside callbacks. And I recently got hired into a web development firm that wanted a Python developer just like me. So I decided to learn JavaScript. That undefined vs null causes a little bit of problems. Once I knew the distinction: const, let, var undefined, null object, array, map, set. I also knew JavaScript classes were fake. I was ready.

Doing great. Here's a dare for you: Make a tutorial video of half an hour in QBasic Language.

Thanks for sharing.that is informative

Hey mosh, are we expecting new courses from you, I asked you because I love your courses 😊

Great ❤❤❤

Web sites demand more resources than video games these days

Where did u get that meme, can u share with us

Hey Mosh could you do a caching course, like redis

I just started learning js this month

Honestly I kinda love the speed to prototype in JavaScript, even knowing the risk of accruing insane technical debt is a perpetual risk with how quiet the language is about the dev's mistakes. I dunno, I'd rather just take the type coersions in JS than C segmentation faults and Java verbosity.

This validate my hate🤣 but i gat to learn it for my bills😭

Is it possible talk about world strtengthest chess software Sockfish 16.1 heard part of software uses C++???

Thanks for this. I'd also add the screwball syntax. Seems like you can't write a function without tossing in some blank pairs of parens and braces. What a mess.

sir you better update your course in your website about React native because is it so old version of documentation React Native 0.62 and now React Native 0.72

Do you think it is worth learning javascript to use it in frontend and backend if not what do you recommend

Matter of preference. Some when they see complications they stop learn that thing. But i think developers should be vast knowledgeable in every tool out there. But who I'm i but people choose what they like

I went through BASIC, C++, Pascal (later Delphi) and finally settled on C# for 2 decades. Once over lunch we were discussing JS with colleagues who used it. I said I hate it. They asked why. Not that they were surprised; they just wanted to hear my version. I said: "I feel like coding in JS compared to C# is like going to a ballroom party in your pyjamas. Not that it can't be done. It just doesn't ever feel right". For the short while I was sentenced to using JS, I remember I spent more than half a day once just chasing a bug due to null checking errors. That's criminal if you ask me. Horrible thing JS. I will not dignify it by calling it a language.

I find TS helpful. Especially libraries built with ts.

MySQL has the motto "garbage in, garbage out" , and no one complains about that. You cant add objects, you should expect to get nonsense back in a scripting language that aims to keep running. The real reason devs hate JS is because it doesn't tell them exactly what to do and how to do it. If you keep removing flexibility, you'll end up with a tool that's so terse, it'll make more sense to automate it than let you toy with it.

I love JavaScript❤

Now make a video with how to cope with these shortcomings

Mr mosh man I love you ❤

There is another alternative to JavaScript, beside TypeScript: Dart/Flutter. When compiled/run for the web it is automatically translated to JavaScript. And Dart if a safe and consistent language. Both type-safe, and null-safe. So a lot of bugs are simply prevented by the language itself. Of course, a scricter language requires greater design and programming skills; therefore you need to be a pro.

Can we get a full Sveltekit course please? I'll give you all my money.

Is it popular or is it simply the default for front end?

Also tools like Babel and Typescript wreak havoc on your debugging experience.

I use wysiwyg and I don't have to program in html anymore

That's why I love it! hahah

Typing always gets me. I can assign a variable as a string, then make it a boolean, then finally a date. I know TypeScript fixes this, but you can still sign multiple types to variables in TypeScript. So your variables can be unpredictable when debugging someone else's code.

I didnt like it because the intellisense wasnt there and troubleshooting it was needed a browser that dont give all the data... but could do all programming though... but if someone writes in html javascript and you need to change it, it is headache as you cant troubleshoot and have to do fast code reading like me and fix it or make it better

Where is @2:16 from?😂

My first paid project was a telegram bot which I created using NodeJS. So I assigned price as number, but admin entered it with comma. All the posts he created had undefined on price 😂😂

What is your upcoming course mosh

The chaos is what makes it beautiful

I mainly use C# for backend development and learning JavaScript was a breeze after learning C#. I honestly don’t get the hate. Debugging is not horrible if you use console.log along with your browser dev tools

l am busy with HTML & CSS, and after that going straight JavaScript!!!!

I only know C and C++ (they are not the same thing, and learning to write idiomatic C and C++ is like learning a different language, but they do work very similarly under the hood) the idea that null and undefined are two different things ... or that a can equal b and b can equal c but a does not equal c as explained above , yikes ... i dont think i ever wanna learn JS ...

I find this video very funny cause of how true it is, but bruh, I love JavaScript, I do everything with it, typescript is a good one though, since learning typescript, it’s been the go-to, still JavaScript under the hood 😂

So many non-issues. How is [ ] + { } = ? an issue you could possibly run into??? Why would you want to add an empty array to an empty object? I don't understand a real world application of this. Can someone explain why this video includes it?

`this` is a menace

using javascript since 1998 for DHTML website, but never use it as primary/main language programming. website is chaotic thing, you'll never can build it only using javascript without HTML and CSS. I don't care full stack or front-end or whatever it called, just used whatever you want to write.

Over the years it’s become fashionable to hate JS. The rules, with some admitted quirks, are very easy to absorb. Everyone who has ever cited some of those quirks I’ve asked how often they’ve been affected which is almost never. The loose and strict equality is probably the greatest real world quirk

mosh you are just making it complex, in real world, who the hell would add empty arrays and empty array and objects?

You forgot to mention the incredibly resource consumption

Oh yeah

Excuse me. Sorry if it bothers you, can you recommend data recovery software for Android with a 100% success rate?

Typescript should be merged into Javascript. The lack of rules in js destroys the language.

JavaScript is not clear about a lot of stuff but I love it.

Guess what, my 1 programming language is JavaScript and still using it with typescript 😮

I love you Mosh

I might be somehow wrong , but I just logged the outputs of these , both in the browser and in a server env , here is what I get : [] + [] => ' ' ; [] + {} => [object Object] ; [] + {} => [object Object] ; {} + {} => [object Object][object Object]

Personally, I hate OOP so classes means fuck all to me. I work as a Senior DevOps Engineer anyway and we use Python (without OOP).

Hey, lets bring jQuery back. It was fun to use and it was easy. Update that to the date. It had all the capabilities the UI could need. Some improvements here and there and it would have been a good alternative to current library set of javascript library jumble.

console.log({}+[]) => [object,Object] console.log({}+{}) => [object,Object] [object,Object] I try this they are different what you said, Did I do someting wrong?

I hated learning JS and web when forced to work on an internal webapp that was built on bootstrap when Jquery was underpinning it. It made it so confusing and all these frameworks that popup with syntax baggage just made it hell. After that nightmare project I remade their stupid BS template and theme widgets in raw HTML5, CSS, and JS6. Not only did I learn real web dev the website was lean and fast and maintainable by any competent programmer. Those frameworks seem great but the time it appears to save gets paid for later tracing odd bugs or security issues back to your 10 megs of black-box lib imports because FOSS is assumed to be reliable too often.

i hate it and it doesn't pay my bills yet :(

JS isn't perfect (no language is), but people hate on it because they think hating it will in-group them, or for content-creator clout -- contributing to the previous. Coming from JS to Python, there are some nice things about it, but I mostly prefer JS (and TS even more -- it's not that hard to pick up if you know JS). If I'd mostly worked with Python before, though, I suspect I'd have a different opinion. In the future I want to pick up languages like Go and Elixir, and I fully expect to have substantial dislike for parts of the experience.

It's true that JavaScript got some weird behaviours that would sometimes make you scratch your head for hours.

😂😂 love the illustrations.

I saw a lot of memes about JavaScript being trash but I never used it myself. I went straight to TypeScript and honestly I like it. Python and TypeScript are my top languages.

Its typescript who stopped me quitting Javascript 😐

There's no thumbs-up button :-/ ... not sure what's going on with YT these days. Learning JS right now, agree on all points you make, coming from Java/Python/C# this languages has lot of strange "rules".

I recently started to use TS in project and... I clench my teeth everytime i need to do something and i comfort myself that's a work that i do for future me.

whener one is coding,one should be very carefull thats why i love typescript

the technology that enables bloatware and all those trackers.

I love it more than I hate it

yeap , js is weird and awesome at the same time !

These are what make Javascript the best programming language.

PHP has suffered hate for decades and survived, its JavaScript turn! Like JavaScript they both put food on the table.

I use webassembly C# Blazor, and try to forget Javascript since then.

I don't hate JavaScript, but I can't say the same about the ecosystem

That's why typescript makes Javascript better.

One more thing: In some methods, I can not use FOR loops. The application just ignores my FOR loop. That's why I must use "recursive functions" in API requests or in some methods to iterate. It is also funny that In some cases, I am allowed to use "for in" or "for of" loop but still can not use regular "for i++" loop 🤣

Anyone here with JavaScript ebook? Thank you!

it doesn't matter if {}+{}=0 or anything bcz there's no rational developer will do it in real world projects so javascript is the best

JS is complicated for beginners or messy developers. You can do things in hundreads of ways and more than half of them are wrong. The hard part of JS is just about learning discipline, cleaness and simplicity. You can do everything with a functional approach without classes and without using this and its contexts. An average developer typically write crap with JS. An advanced one would write very elegant code. Mastering JS is not easy, this is why people hate it. A well written JS code is thousands of time more concise and elegant than a python one.

It pays the bill 😂❤

If you want to be a frontend wizard, you have no choice to master js html css. That is life.

Doesn't matter. Dont do what is easy, do what is recommended. The largest tech companies meta and google created JS frameworks react and angular which means both will be promising so doesn't matter if easy or not, learn what is used the most.

Typescript is a Language ❌ Typescript is a Linter ✔

why can't python be used for frontend ? i know python and i think it's very good and can do everything then why not web development

Because it's so difficult to program

JS in the frontend ? Love it. JS is the backend, ai, mobile ? Hate it.

Becuase Flutter(dart) is much better and easier and full stable language

These coercion quirks brought up in the video are only a theoretical problem and not really an issue when writing applications with javascript. Most of javascript's language issues are mitigated if you activate your brain. But people are lazy. I get it. They don't want to educate themselves. But true, the non existent type system make intellisense impossible which forces you to always lookup things in the documentation.

I wish Spring team could create new front end framework with Java, that can run on android, iOS and website, so I dont have to use this JS 😂

Drizzle didn't remove TypeScript. Drizzle team was dunking on DHH for his decision to remove TypeScript. It was a joke on Twitter.

Because it is not OOP, but tries to lean into it.
