Like most modern programming languages, JavaScript supports associative arrays. The index in associative arrays is a string (including blanks). For example, the following code initializes a two-element associative array:

  var a = new Array();
  a["The day after Sunday"] = "Monday";
  a["The day after Monday"] = "Tuesday";
Let's test the value of the first and second elements.
