Probably the most informative video I've seen about the subject. May I ask what extension you are using that shows the errors and logs in red/green in real time as you write the code?
I would like you to ask a question where do you find the image that perfectly fit in webpage video and the coloring to the page. When i try it i fail to find the image for by website. So, i need you help because i am at learning phase in short a fresher.
So what I'd be really interested in is: Why are we taught to never ever use var anymore? I can see some use cases for it, but I've always been told to only use let and const.
@@thyran6288 I looked it up since I left this comment. As someone who has never used var, my first thought was to use it as easy global variables or as a kind of a state. But turns out that makes no sense, you're basically just saving that one line of code "let someGlobalVariable" and making the code more difficult to follow.
@@picture_of_a_swan Yeah, exactly. Plus now you don't even get errors any more when you don't have a value. I see that maybe one could argue that this undefined state is exactly what you would use it for, but you would just use it to check if a value exists and then you could just use a let again. I can however see the use in legacy code, where Typescript or modules were not the standard, I believe it was the easiest way to make your scripts reuse your variables. Sometimes this could have been beneficial, but I'd always prefer the capsulation that modules provide. It is so much more readable and elegant
btw, guys have you ever try to zoom out your websites? , it distorts when I do , if you guys spam the comment section with this issue , may be he will make a video on that.
Why would anyone even use var? It is way more prone to unexpected results and if you really need it to not throw an error before it is assigned, you could just use a let and initialize it with undefined. Not to mention that it makes the code way harder to read. I personally do not ever see a use case for var and would always consider using let instead when a variable should be able to be reassigned
Would you like to see more content on this topic?
Js plz
Yes.. yes..🦾😁
Yes boss..plz make video of js tutorial ...

It's good to learn the differences because, at some point, you might face 'var'. Keep in mind NEVER to use it in your code. Only 'let' and 'const' ✌🏻
After 1 year , i finally learned the difference between let and var; it was so similiar
I like that you're not just making videos about css only, but trying some new topics. That's exciting, thanks

Do tell, I would love to know about a genuine use case where let is not the preferred choice if there is any
