string.prototype.trimright

String.prototype.trimRight

A ES2019-spec-compliant String.prototype.trimRight shim. Invoke its "shim" method to shim String.prototype.trimRight if it is unavailable.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec. In an ES6 environment, it will also work properly with Symbols.

Most common usage:

var trimRight = require('string.prototype.trimright');
 
assert(trimRight(' \t\na \t\n') === 'a \t\n');
 
if (!String.prototype.trimRight) {
    trimRight.shim();
}
 
assert(trimRight(' \t\na \t\n ') === ' \t\na \t\n '.trimRight());
