Access Character in String using []

In JavaScript, you can access individual characters in a string using square bracket notation, as shown in the following.

Syntax

str[n]

where

• str is a string
• [] is square bracket notation
• n is index

str[n] returns the character from the string str present at the index n.

Examples

1. In the following program, we get the character in string name at index=3.

let name = 'apple';
let output = name[3];
console.log(output);

2. In the following program, we take a value from index n, such that this index is out of the range for given string length. str[n] returns undefined.

let name = 'apple';
let output = name[15];
console.log(output);
