JavaScript Arrays

   
JavaScript Arrays

An array in JavaScript is a versatile data structure used to store multiple values in a single variable. Arrays can hold various data types, including numbers, strings, and Boolean values.

To create an array, you start with an opening square bracket [, list your values separated by commas, and end with a closing square bracket ].

For example:

var arrayName = ['labw3', 235, true];

In this example, the array contains three different data types: a string ('labw3'), a number (235), and a Boolean (true).

Here are some key points about arrays in JavaScript:

  • String Values: Enclose string values in single or double quotes.
var stringArray = ['apple', "banana"];
  • Numbers and Booleans: Numbers and Boolean values do not require quotes.
var mixedArray = [123, false, 3.14];

Arrays are a fundamental part of JavaScript, providing a way to organize and manipulate collections of data efficiently.
