Javascript Array inside Array - how can I call the child array name?

Question

Here is the example of what I am doing:

   var size = new Array("S", "M", "L", "XL", "XXL");
   var color =          


        

Answer 1

In that case you don't want to insert size and color inside an array, but into an object

var options = { 
    'size': size,
    'color': color
  };

Afterwards you can access the sets of keys by

var keys = Object.keys( options );
