Wouldn't the IDE pointed it out?

[–] joneskind@lemmy.world 17 points 1 year ago (3 children)

Yes.

Besides, Javascript doesn't need semicolon since 2016.

Wait, did you just made a meme of my comment?

Awesome!

Glad you take it like a champ :)

Automatic Semicolon Insertion (ASI) has (sadly) been a part of JavaScript longer than 2016. I'm not sure exactly when it was introduced, but this document from 2009 already contains it: https://web.archive.org/web/20120418215856/https://ecma262-5.com/ELS5_Section_7.htm#Section_7.9

IMO it's bad practice to rely on ASI since the semicolons may not get inserted where you expected them to. The following snippet

const x = 0
const y = x
[1, 2, 3].forEach(console.log) 

is interpreted as

const x = 0;
const y = x[1, 2, 3].forEach(console.log);

which raises a TypeError.

There are more examples of ASI not doing the right thing on the web, so I don't agree with "Javascript doesn't need semicolon".

As Mark Twain said, “Never discuss politics, semicolons, tabs, or religion in polite company.”

Use an autoformatter for all code (both in the editor on save/type and as CI check).

There is no problem anymore.

Only someone who is really into mental torture would not use a linter.

Obviously, you patch the IDE so it doesn't

[–] dandroid@dandroid.app 22 points 1 year ago (1 children)

The IDE will tell you and fix it for you.

Not if they use GNU nano or that shitty windows notepad.

Jokes on them I don’t use semicolons in JavaScript
