How to Get Only the First 10 Characters from a String in JavaScript

When working with strings in JavaScript, it’s common to need to extract only a specific portion of a string. In this article, we will focus on extracting the first 10 characters from a string. We will explore different methods to achieve this task efficiently.

Method 1: Using the substring Method

The substring method in JavaScript allows us to extract a portion of a string based on specified indices. Here’s how you can use it to get the first 10 characters from a string:

const originalString = "Hello, World!";
const firstTenCharacters = originalString.substring(0, 10);
console.log(firstTenCharacters);

In this code snippet, we define a string originalString and then use the substring method to extract the characters from index 0 to index 9 (10 characters in total).

Method 2: Utilizing Array Destructuring

Another approach to extract the first 10 characters from a string is by converting the string into an array and then using array destructuring:

const originalString = "Lorem Ipsum is simply dummy text";
const [firstTenCharacters] = [...originalString].slice(0, 10);
console.log(firstTenCharacters);

Here, we convert the originalString into an array using the spread operator [...originalString], then use slice to get the first 10 elements of the array and finally use array destructuring to extract the first 10 characters.

Conclusion

In this article, we explored two different methods to get only the first 10 characters from a string in JavaScript. By using the substring method or array destructuring, you can efficiently extract the desired portion of a string. Experiment with these methods in your projects to enhance your string manipulation skills.
