no-space-before-semi

Disallows spaces before semicolons.

::: important This rule was removed in ESLint v1.0.0 and replaced by the semi-spacing rule. :::

JavaScript allows for placing unnecessary spaces between an expression and the closing semicolon.

Space issues can also cause code to look inconsistent and harder to read.

var thing = function () {
  var test = 12 ;
}  ;
