How best to do a JavaScript array with non-consecutive indexes?

Question

I\'m writing a Google Chrome extension, in JavaScript, and I want to use an array to store a bunch of objects, but I want the indexes to be specific non-consecutive

Answer 1

I would use an object to store these. You can use numbers for properties using subscript notation but you can't using dot notation; the object passed as the key using subscript notation has toString() called on it.

var obj = {};
obj[471] = {foo: "bar"} ;
