Separate two strings to two variables

Let's say I have this :

var colors = 'Red,Blue,Green,Orange,White,Brown';

I tried to parse it to get all the colors which means : 

color1='Red';
color2='Blue';
[...]

I used to use the matches() and then put a comma since the colors are separated by commas so I put ',', but the result is not what I've expected... Is there any fast way to do it?

If you dont mind to have it on the global object:

'Red,Blue,Green,Orange,White,Brown'.split(',').forEach(function(color, index ){
  window['color' + index] = color;
});

To match it with a regular expression you just need to use \w+ which matches any of the following characters A-Z a-z 0-9 _.

var colors = 'Red,Blue,Green,Orange,White,Brown';
var matches = colors.match(/\w+/g);
console.log(matches[0]);

If you are worried about matching the numbers and underscore, you can always just use /[a-z]+/gi

Yep, I recommend you to use split()

As the docs says :

The split() method is used to split a string into an array of substrings, and returns the new array.

Tip: If an empty string ("") is used as the separator, the string is split between each character.

Note: The split() method does not change the original string.

So you could get the same of your colors doing something like this :

var colors = 'Red,Blue,Green,Orange,White,Brown'.split(','); //use .split() to split the character you want to.
var color1 = colors[0];
var color2 = colors[1];
var color3 = colors[2];
[...]
alert("Color 1 = " +color1 + "\n"+ "Color 2 =  " + color2);

Now you could do some logic to know the items that are on your var colors or whatever you want.

Hope it helps.
