JavaScript Arrays

Learn how to create and use arrays in JavaScript.

Nested Arrays in JavaScript

10 June 2008 / 13 Comments

In previous tutorials we’ve taken a look at JavaScript array basics, manipulating arrays, and sorting arrays. So far, all the arrays we’ve dealt with have been “flat” arrays; each array element contains a single value, such as a number, string, or object.

However, like most programming languages, JavaScript lets you create arrays inside arrays, known as nested arrays. In a nested array, the elements of one array are themselves arrays. For example:

Sorting JavaScript Arrays

Previously we looked at the basics of JavaScript arrays, and showed how to manipulate the elements within them. In this tutorial, we take a look at how to sort array elements. You learn how to reverse the order of an array; how to sort an array alphabetically; and how to sort an array’s elements into any order you like.

My first tutorial on JavaScript arrays covered the basics: creating arrays, accessing the contents of arrays, array lengths, and looping through arrays.

In this tutorial, you explore arrays in more depth, and learn how to use various methods of the Array object to manipulate arrays.

JavaScript Array Basics

5 May 2008 / 4 Comments

Like most languages, JavaScript lets you create arrays to store bunches of values in. An array is simply a sequence, or list, of values. A value in a JavaScript array can be anything from a number or string, through to a function or an object; JavaScript arrays can store pretty much any type of data. A single value in a JavaScript array is called an element.

With JavaScript arrays, you can:

  • Store any number of values, including no values at all (known as an empty array)
  • Access any or all the elements of an array through a single variable name
  • Read and write elements of an array
  • Loop through all the elements of an array
  • Join two or more arrays together to make one longer array
  • Convert an array to one long string
  • Add or remove elements from the beginning, end, or middle of an array
  • Reverse the order of the elements in an array
  • Sort the elements of an array in any order you like
  • Nest arrays within other arrays

JavaScript stores arrays as Array objects, so most of the things you can do with arrays revolve around the properties and methods of the Array class.

In this introductory article, you look at creating arrays, accessing the contents of arrays, the concept of array lengths, and looping through arrays.
