How to Parse a String in Javascript?

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(/-/);
as amber and sinan have noted above, the javascritp '.split' method will work just fine. Just pass it the string separator(-) and the string that you intend to split('123-abc-itchy-knee') and it will do the rest.
var coolVar = '123-abc-itchy-knee';
var coolVarParts = coolVar.split('-'); // this is an array containing the items
var1=coolVarParts[0]; //this will retrieve 123
To access each item from the array just use the respective index(indices start at zero).
