This rule is deprecated, and will eventually be removed.
Why is this an issue?
Extra semicolons (;) are usually introduced by mistake, for example because:
- It was meant to be replaced by an actual statement, but this was forgotten.
- There was a typo which lead the semicolon to be doubled, i.e.
;;.
- There was a misunderstanding about where semicolons are required or useful.
Noncompliant code example
var x = 1;; // Noncompliant
function foo() {
}; // Noncompliant
Compliant solution
var x = 1;
function foo() {
}
Exceptions
This rule does not apply when the semicolon is after a line break and before ( or [ as it is often used in semicolon-less
style.
var hello = 'Hello'
var world = 'World!'
var helloWorld = hello + ' ' + world
;[...helloWorld].forEach(c => console.log(c))
var a = 1
var b = 2 * a
;(a + b).toString()
