segregate value by _ using jquery like explode

var str   = "my car is red";
var stringArray = str.split(/(\s+)/);

console.log(stringArray); // ["my", " ", "car", " ", "is", " ", "red"] 

var myString = 'IE, Firefox, Opera, Chrome, Safari';
var myStringArray = myString.split(',');

The values are now in myStringArray - myStringArray[0] would be 'IE'
