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'
