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).
