String.prototype.trimRight()

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The trimRight() method removes whitespace from the right end of a string.

The following example displays the lowercase string ' foo':

var str = '   foo  ';

console.log(str.length); // 8

str = str.trimRight();
console.log(str.length); // 5
console.log(str);        // '   foo'
