How to check if a string “StartsWith” another string?

Question

How would I write the equivalent of C#\'s String.StartsWith in JavaScript?

var haystack = \'hello world\';
var needle = \'he\';

haystack.startsWith(needle)

I just learned about this string library:

http://stringjs.com/

Include the js file and then use the S variable like this:

S('hi there').endsWith('hi there')

It can also be used in NodeJS by installing it:

npm install string

Then requiring it as the S variable:

var S = require('string');

The web page also has links to alternate string libraries, if this one doesn't take your fancy.
