minus-square@[email protected]linkfedilinkEnglish18•edit-21 year agoAutomatic 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”.

minus-square@[email protected]linkfedilink2•1 year agoUse an autoformatter for all code (both in the editor on save/type and as CI check). There is no problem anymore.
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 :)
