Foil 31 Arrays in JavaScript - I

From JavaScript Tutorial for Certificate Course UC Web applications Certificate -- Summer 97. by Geoffrey C. Fox, Tom Scavo

In Navigator 3, we write:

var area = new Array();

area[0] = "Alabama";

area[1] = "Alabama";

area[2] = "Alaska"; // etc.

var acode = new Array();

acode[0] = 205; // mapping area codes to states

acode[1] = 334;

acode[2] = 907;

area.length gives the length of the array ( 3 in this case)

Note you can set array elements to be objects to make arrays of objects:

menuArray = new Array();

menuArray[0] = new MenuObject(1, 'world');

worldMenu = menuArray[0]; // a synonym
