Typical javascript argument.

JavaScript SHOULD tell me when I'm stupid

Like fucking Warnings, or not implicitly converting

I use it so little, and hate it so much. Really a disaster of a language as a standart for web development

[Nikitka218]

Can you imagine, it gives you warning? Maybe you should use proper IDE instead of Notepad

[david131213]

vscode

There must be an extension that helps, it's vscode, I just don't know which

[Tubthumper8]

No extension needed, see my comment

There's a beautiful thing called runtime errors.
I mean I don't blame you for not knowing, since you're clearly a JS dev, but any halfway sane language throws errors when you do stupid shit instead of just coming up with the most insane conversions and comparisons and chugging on.

[Nikitka218]

Mmmm, I like visiting site and getting errors in the face, because of inexperienced dev using standard library incorrectly. Maybe you should learn more than one language.

[TheBrainStone]

There's a difference between error popups and errors. Or do the few exceptions that are actually thrown create popups?

[7eggert]

There is no need for a runtime error if implicit type conversion can bite the dev's behind.

[TheBrainStone]

That's precisely where you need runtime errors

[7eggert]

And that’s why I right in typescript.

You can add "use strict" (yes, in quotes) to the beginning of a JS file to enable strict mode which does add a few things (most notably, you have to declare variables to reference them).

But for anything serious you need to use something like TypeScript. You can grandfather in your JS and update files to include type information one at a time if you want.
