Declaring Arrays

After completing this module, you are expected to:

• Represent a group of similar data using arrays.
• Create arrays and define its elements.

          For groups of similar data, most high-level computer programming languages have ways to be collected together and referred to by a single name. One of the most widely used techniques is the array. An array contains a data set represented by a single variable name. You can use an array when you want to store a group or a list of related data in a single, easily controlled location.

          In this learning guide we will take a look at this technique and learn how to use it in JavaScript.
