How Can I Get Last Characters of a String

How can I get the last characters of a string?

When working with JavaScript, there may be times when you need to extract the last characters of a string. Whether you want to display a specific portion of a string or perform some manipulation, there are multiple ways to achieve this. In this blog post, we will explore three different solutions to help you get the last characters of a string.

1. Using the slice() method

The slice() method allows you to extract a portion of a string and returns a new string containing the extracted characters. To get the last characters of a string, you can pass a negative value as the starting index to the slice() method.

const str = "Hello, World!";
const lastCharacters = str.slice(-5);

console.log(lastCharacters); // Output: World!

In the above example, the slice() method is used with a starting index of -5, which means it will extract the last 5 characters of the string "Hello, World!".

2. Using the substring() method

The substring() method is similar to the slice() method and allows you to extract a portion of a string. However, unlike the slice() method, the substring() method does not accept negative indices.

const str = "Hello, World!";
const lastCharacters = str.substring(str.length - 5);

console.log(lastCharacters); // Output: World!

In the above example, the substring() method is used with the starting index calculated as str.length - 5. This will extract the last 5 characters of the string "Hello, World!".

3. Using the substr() method

The substr() method allows you to extract a specified number of characters from a string, starting from a specified index. To get the last characters of a string, you can pass a negative value as the starting index to the substr() method.

const str = "Hello, World!";
const lastCharacters = str.substr(-5);

console.log(lastCharacters); // Output: World!

In the above example, the substr() method is used with a starting index of -5, which means it will extract the last 5 characters of the string "Hello, World!".

Now that you have learned three different ways to get the last characters of a string in JavaScript, you can choose the method that best suits your requirements. Whether it’s using slice(), substring(), or substr(), you can easily extract the desired portion of a string and manipulate it as needed.

Happy coding!
