String.prototype.trimEnd()

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

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

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

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.

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";

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'
