Disallow Spaces Before Semicolon (no-space-before-semi)

Replacement notice: 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.

The following patterns are considered warnings:

var foo = "bar" ;

var foo = function() {} ;

var foo = function() {
} ;

var foo = 1 + 2 ;

The following patterns are not warnings:


var foo = "bar";


This rule was introduced in ESLint 0.4.3 and removed in 1.0.0-rc-1.
