Creating a Javascript Function to Find Characters from ASCII Values

Hello there, programmer! Welcome to the blog post. Today we are diving into the intricate world of Javascript, focusing on a specific task – programming the function findCharacterFromASCIIValue. Don't worry, we'll keep it approachable and jargon-free. The aim is to give you a clear and calm walkthrough of the steps necessary to achieve this. So, let's delve in and discover the functionality of this interesting feature. Let's code!

Step 1: Understanding the Problem

The task is to create a function that would take an ASCII value as an input and return its corresponding character. ASCII value is a numerical representation of characters that we use in computer memory. Each character has a unique ASCII value.

js
let asciiValue = 65;

Step 2: Embed the Char From ASCII Function

In JavaScript, there is a built-in method called String.fromCharCode(). This method converts ASCIIs to characters.

js
let char = String.fromCharCode(asciiValue);
// Value of char is 'A'

Step 3: Wrap the Process Into a Function

We'll wrap the last step into a function named findCharacterFromAscii. This function takes an ASCII value as an argument and returns the corresponding character.

js
function findCharacterFromAscii(asciiValue) {
    let character = String.fromCharCode(asciiValue);
    return character;
}

Step 4: Calling the Function

We'll call the findCharacterFromAscii function and pass an ASCII value of 66 to it.

js
let result = findCharacterFromAscii(66);
// Value of result is 'B'

Step 5: Conclusion

Here is the full code that implements the function. The findCharacterFromAscii function takes ASCII values as input and uses JavaScript's built-in String.fromCharCode() method to return the corresponding characters.

js
function findCharacterFromAscii(asciiValue) {
    let character = String.fromCharCode(asciiValue);
    return character;
}

let result = findCharacterFromAscii(66);
console.log(result); // Outputs: 'B'

Mathematical principle

ASCII (American Standard Code for Information Interchange) is a character encoding standard where each character is represented by a number. In this case, we use these ASCII values to find the corresponding character. The `String.fromCharCode()` method in JavaScript is used to get the character from the ASCII value.
