trimEnd() trimRight()
None.
A new string representing str
stripped of whitespace from its end (right side). Whitespace is defined as white space characters plus line terminators.
If the end of str
has no whitespace, a new string is still returned (essentially a copy of str
).
After trim()
was standardized, engines also implemented the non-standard method trimRight
. However, for consistency with padEnd()
, when the method got standardized, its name was chosen as trimEnd
. For web compatibility reasons, trimRight
remains as an alias to trimEnd
, and they refer to the exact same function object. In some engines this means:
String.prototype.trimRight.name === "trimEnd";
The following example trims whitespace from the end of str
, but not from its start.
let str = " foo "; console.log(str.length); // 8 str = str.trimEnd(); console.log(str.length); // 6 console.log(str); // ' foo'
