How to parse a string in JavaScript?

Question

I'm just curious how I go about splitting a variable into a few other variables.

For example, say I have the following JavaScript:

var coolVar = '123-abc-itchy-knee';

And I wanted to split that into 4 variables, how does one do that?

To wind up with an array where

array[0] == 123
and
array[1] == abc

etc would be cool.

Or (a variable for each part of the string)

var1 == 123  
and 
var2 == abc

Could work... either way. How do you split a JavaScript string?

Use the Javascript string split() function.

var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');

// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc

Use split on string:

var array = coolVar.split(/-/);
