- An ES5 spec-compliant `String.prototype.trim` shim. Invoke its "shim" method to shim `String.prototype.trim` if it is unavailable.
- This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the spec (both [ES5](https://262.ecma-international.org/5.1/#sec-15.5.4.20) and [current](https://tc39.es/ecma262/#sec-string.prototype.trim)).
- Most common usage:
- ```js
- var assert = require('assert');
- var trim = require('string.prototype.trim');
- assert(trim(' \t\na \t\n') === 'a');
- trim.shim(); // will be a no-op if not needed
- assert(trim(' \t\na \t\n') === ' \t\na \t\n'.trim());
- ```
- ## Engine Bugs
- Some implementations of `String#trim` incorrectly trim zero-width spaces. This shim detects and corrects this behavior.
- ## Tests
- Simply clone the repo, `npm install`, and run `npm test`
