Create array literal

Create Array Literal

An array is a collection of values stored in a single variable. In JavaScript, arrays are created using array literals, which are a list of comma-separated values enclosed in square brackets [].

Example:

var fruits = ['apple', 'banana', 'orange', 'kiwi'];

In this example, we have created an array of fruits. The values 'apple', 'banana', 'orange', and 'kiwi' are enclosed in square brackets [] and separated by commas. The array is assigned to the variable 'fruits' using the assignment operator (=).

There are multiple ways to create an array literal in JavaScript:

  • You can create an empty array by providing no values inside the square brackets.
  • You can create an array with a single value by providing only one value inside the square brackets.
  • You can create a multidimensional array by nesting arrays inside other arrays.

Empty Array:

var emptyArray = [];

In this example, we have created an empty array. Since there are no values inside the square brackets [], the array is empty.

Array with a Single Value:

var singleValueArray = ['hello'];

In this example, we have created an array with a single value. The value 'hello' is enclosed in square brackets [] and assigned to the variable 'singleValueArray'.

Multidimensional Array:

var multidimensionalArray = [['John', 'Doe'], ['Jane', 'Doe']];

In this example, we have created a multidimensional array. The array contains two nested arrays, each containing two values. The array is assigned to the variable 'multidimensionalArray' using the assignment operator (=).
