ES6 String.prototype.startsWith polyfill 

A robust & optimized polyfill for the String.prototype.startsWith method in ECMAScript 6.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.

Other polyfills for String.prototype.startsWith are available:

* by Paul Miller (~~fails some tests: 1, 2~~ passes all tests)
* by Google (~~fails a lot of tests~~ now uses this polyfill and passes all tests)

Installation

Via npm:

``bash
npm install string.prototype.startswith
`

Then, in Node.js:

`js
var startsWith = require('string.prototype.startswith');
`

In a browser:

`html

`

> NOTE: It's recommended that you install this module using a package manager
> such as npm, because loading multiple polyfills from a CDN (such as bundle.run)
> will lead to duplicated code.

Notes

Polyfills + test suites for String.prototype.endsWith and String.prototype.contains are available, too.

For maintainers

$3

1. On the main branch, bump the version number in package.json:

`sh
npm version patch
`

Instead of patch, use minor or major as needed.

Note that this produces a Git commit + tag.

1. Push the release commit and tag:

`sh
git push && git push --tags
``

Our CI then automatically publishes the new release to npm.
