ASCII is the abbreviation for American Standard Code for Information Interchange.
This is an information standard, similar to unicode, that defines a standard for the representation of text and other information in computers.
In more simpler terms, it basically assigns a unique code for each character in a text.
For example, the letter
a has the code
97 in ASCII.
To learn how to convert an ASCII code to a character, let's start with the code we want to convert.
const code = 97;
Now we can use this along with the
String.fromCharCode() method to convert the code to a character.
const code = 97; const character = String.fromCharCode(code); console.log(character);
This method is simple, it takes a single parameter, which is a number representing the ASCII code of the character we want to convert.
It will return back a string, which is the character we want.
The cool thing about this method is that it can convert multiple ASCII codes at once and return it in a single string.
const codes = [97, 98, 99]; const characters = String.fromCharCode(...codes); console.log(characters);
Alternatively, you can just pass them one by one, like this:
const string = String.fromCharCode(97, 98, 99); console.log(string);
If you want, you can instead get back an array of the converted strings by using the
const codes = [97, 98, 99]; const characters = codes.map(code => String.fromCharCode(code)); console.log(characters);

In this post, we learned how to convert an ASCII code to a character, and how to convert multiple ASCII codes at once.
Simply use the
String.fromCharCode() method which takes the number you want to convert and returns the character.
