how to declare arrray

Example 1 – Array Constructor

1 2 3

// Declare an array (using the array constructor) var arlene1 = new Array(); var arlene2 = new Array("First element", "Second", "Last");

Example 2 – Literal notatoin

1 2 3

// Declare an array (using literal notation) var arlene1 = []; var arlene2 = ["First element", "Second", "Last"];

Example 3 – Implicit Declaration

1 2 3

// Create an array from a method's return value var carter = "I-learn-JavaScript"; var arlene3 = carter.split("-");

To avoid script errors, you should get into the habit of initializing an array when you declare it, like so:

1 2 3

// Declare an empty array using literal notation: var arlene = []; // The variable now contains an array of length zero
