JavaScript Start all javascript scripts with ;? [closed] javascript scripts start

Do bother, more and more people leverage the power of ASI and write semicolonless JavaScript. In semicolonless JS world that's the "rule", you put a semicolon before raw expressions, like ;(), or ;[] or ;//, as well as after 'use strict'; and omit them everywhere else. Raw expressions are not very common, except the typical IIFE. Even if you write JS with semicolons, that particular one is safe and will do more good than bad.

not a good idea:

  2. stuff wont work on your site with no clear indication as to why

Answer:2

The leading semicolon is actually pretty useful if you split and decouple a lot of code into several javascript files, which you at some point, concatenate to create a production file.

It will simply help to avoid errors in constructs like

(function() {
}())

if all your files are wrapped in constructs like this, it fill fail without any semicolon, separating them. Other than that, there isn't much value in that pattern.
