Get First 3 Characters of a String in JavaScript

In this tutorial, we will learn how to get the get the first 3 characters of a string in JavaScript with the help of examples.

Note: In JavaScript, strings are the sequence of characters, where the index of the first character is 0, the second character is 1, third character is 3 etc.

Getting the first 3 characters of a string

To get the first 3 characters of a string, we can use the built-in substring() method by passing the 0, 3 as an arguments to it.

Where 0 is the start index, 3 is the end index which is excluded from the output.

Here is an example:

const place = "Paris";

const firstThreeCharacters = place.substring(0, 3);
console.log(firstThreeCharacters);

Output:

"Par"

In the example above, we have passed 0, 3 as an arguments to the substring() method. So it begins the extraction at index 0 and extracts before the index 3 of a string.

Alternatively, we can also the slice() method in JavaScript, to access the first 3 characters in the string.

Here is an example:

const place = "Paris";

const firstThreeCharacters = place.slice(0, 3);
console.log(firstThreeCharacters);

Output:

"Par"

The slice() method takes the two arguments, the first argument is start index and the second argument is end index then it returns a new string between the start index and end index (that is excluded from the output).
