How to get the last character of a string in JavaScript ?

In this article, we have given a string of size len, the task is to get the last character of a string using JavaScript. There are several methods to solve this problem some of which are discussed below:

Methods to Get the Last Character of a String:

Using charAt() Method
Using str.slice() Method
Using str.substr() Method
Using JavaScript str.length for index
Using String.at() method
Using String.match() method

Method 1: Using charAt() Method:

This method returns the character at a given index.

Syntax:

character = str.charAt(index)

First, count the number of characters in a given string by using the str.length property. Since the indexing starts from 0 so use str.charAt(str.length-1) to get the last character of the string.

Example: This example implements the above approach.

Javascript

// Input String
let str = "GeeksforGeeks";
 
// Getting last character using char at
let res = str.charAt(str.length - 1);
 
// Display output
console.log(res);

Output

Method 2: Using str.slice() Method

The string.slice() function is used to return a part or slice of the given input string.

Syntax:

str.slice(startingindex, endingindex)

Example: This example uses the slice() function to get the last character of the string.

Javascript

// Input string
let str = "GeeksforGeeks";
 
// Getting last character using slice method
let res = str.slice(-1);
 
// Display output
console.log(res);

Output

Method 3: Using str.substr() Method

The str.substr method returns the specified number of characters from the specified index from the given string.

Syntax:

str.substr( start_index, Length_sub_str );

Example: This example uses str.substr to print the last character of the string.

Javascript

// Input string
let str = "GeeksforGeeks";
 
// Getting last character using substr method
let res = str.substr(-1);
 
// Display Output
console.log(res);

Output

Method 4:Using JavaScript str.length for index

Using string indexing, we can use string indexing to access the element of the array and use the length property of the string to access the last element index

Syntax:

str[ str.length-1 ];

Example: This example uses string indexing to print the last character of the string.

Javascript

// Input string
let str = "GeeksforGeeks";
 
// Getting last character using str.length
let res = str[str.length-1];
 
// Display output
console.log(res);

Output

Method 5: Using String.at() method

In this method, we can pass -1 for getting the last character of the string.

Syntax:

str.at(-1)

Example: In this example, we will use str.at() for getting the last character.

Javascript

// Input string
let str = "GeeksforGeeks";
 
// Getting last character using string.at method
let res = str.at(-1);
 
// Display output
console.log(res);

Output

Method 6: Using String.match() method

In this method, we can search for the last character in the string.

Syntax:

str.match(/.$/g)

Example: In this example, we will use str.match() for getting the last character.

Javascript

// Input string
let str = "GeeksforGeeks";
 
// Getting last charcter using match method
let res = str.match(/.$/g);
 
// Display output
console.log(res);
