String.prototype.trimEnd()

You’re reading the English version of this content since no translation exists yet for this locale. Help us translate this article!

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

Syntax

str.trimEnd();
str.trimRight();

Return value

A new string representing the calling string stripped of whitespace from its (right) end.

Description

The trimEnd() / trimRight() methods return the string stripped of whitespace from its right end. trimEnd() or trimRight() do not affect the value of the string itself.

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'
