String.prototype.trimEnd()

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.

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':

let str = '   foo  ';

console.log(str.length); // 8

str = str.trimEnd();
console.log(str.length); // 6
console.log(str);        // '   foo'
