How to Convert Integer to Its Character Equivalent in JavaScript?
In this article, we will see how to convert an integer to its character equivalent using JavaScript.
Method Used: fromCharCode()
This method is used to create a string from a given sequence of Unicode (Ascii is the part of Unicode). This method returns a string, not a string object.
Javascript
let s = () => { let str = String.fromCharCode( 103, 102, 103); console.log(str); }; s(); //print "gfg" |
Output
gfg

- Integer to Capital characters conversion
- Integer to Small characters conversion
Approach 1: Integer to Capital characters conversion
Example: Using both from CharCode() and, charCodeAt() methods
Javascript
let example = (integer) => { let conversion = "A" .charCodeAt(0); return String.fromCharCode( conversion + integer ); }; // Integer should 0<=intger<=25 console.log(example(6)); console.log(example(5)); console.log(example(6)); |
Output
G F G
Example: Using only fromCharCode() method
Javascript
let example = (integer) => { return String.fromCharCode( 65 + integer ); // Ascii of 'A' is 65 }; console.log(example(6)); console.log(example(5)); console.log(example(6)); |
Output
G F G
Approach 2: Integer to Small characters conversion
Example: Using both fromCharCode() and, charCodeAt() methods:
Javascript
let example = (integer) => { let conversion = "a" .charCodeAt(0); return String.fromCharCode( conversion + integer ); }; // Integer should 0<=intger<=25 console.log(example(6)); console.log(example(5)); console.log(example(6)); |
Output
g f g
Example: Using only fromCharCode() method.
Javascript
let example = (integer) => { return String.fromCharCode( 97 + integer); }; console.log(example(6)); console.log(example(5)); console.log(example(6)); |
Output
g f g
