String.prototype.trimEnd()

The trimEnd() method removes whitespace from the end of a string. trimRight() is an alias of this method.

Syntax

trimEnd()

trimRight()

Return value

A new string representing str stripped of whitespace from its end (right side).

If the end of str has no whitespace, a new string is still returned (essentially a copy of str), with no exception being thrown.

Aliasing

For consistency with functions like String.prototype.padEnd the standard method name is trimEnd. However, for web compatibility reasons, trimRight remains as an alias to trimEnd. In some engines this means:

String.prototype.trimRight.name === "trimEnd";

Examples

Using trimEnd()

The following example displays the lowercase string ' foo':

var str = '   foo  ';

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

str = str.trimEnd();
console.log(str.length); // 6
console.log(str);        // '   foo'
