no-space-before-semi

Disallows spaces before semicolons.

(removed) This rule was removed in ESLint v1.0 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 ;
} ;

Rule Details

This rule prevents the use of spaces before a semicolon in expressions.

Examples of incorrect code for this rule:

var foo = "bar" ;

var foo = function() {} ;

var foo = function() {
} ;

var foo = 1 + 2 ;

Examples of correct code for this rule:

;(function(){}());

var foo = "bar";

Version

This rule was introduced in ESLint v0.4.3 and removed in v1.0.0-rc-1.
