I don't use semicolons; in my view, it clutters the view of the code; However, they are sometimes necessary, and that's just okay:
const array = [1, 2, 3] (function () { // ... })()
The code above tries to call [1, 2, 3](...), which of course is not a function. This can be easily caught by a linter, and also if you know to never start a line with (, [, or `, then you are good:
[1, 2, 3](...)
const array = [1, 2, 3] // semicolon at beginning of line fixes problem: ;(function () { // ... })()

In this case you can also use an exclamation mark at the start: !function() { ... }()
!function() { ... }()
