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'
