findASCIIValue()

Step 1: Understanding ASCII

To solve this problem, you first need to understand what ASCII is. ASCII stands for American Standard Code for Information Interchange. It's a character encoding standard for electronic communication. Each ASCII character corresponds to a number from 0 to 127.

So to get the ASCII value for a character, we simply have to translate the character using this standard.

JavaScript provides a built-in method to achieve this, called .charCodeAt().

Step 2: Creating a Function

Let's start by creating a JavaScript function called findASCIIValue. For now, it will be an empty function.

function findASCIIValue() {

}

Step 3: Accepting Parameters

Our function needs to accept a parameter. This parameter will be the character we will convert to ASCII.

Let's modify the function to accept a parameter:

function findASCIIValue(character) {

}

Step 4: Implementing the .charCodeAt() Method

Inside this function, we will take advantage of the JavaScript built-in method .charCodeAt(). It takes an index as its parameter and returns the Unicode of the character at that index.

Since we provide a single character, we can use 0 as index. As we are sure the first (and only) character is what we want to be turned into ASCII value.

Here's how it looks:

function findASCIIValue(character) {
  return character.charCodeAt(0);
}

This function will now accurately convert a character into its corresponding ASCII value.

Step 5: Testing

Let's test it to confirm it works as expected.

For example, let's find the ASCII value for the character 'A'.

console.log(findASCIIValue('A')); // Outputs: 65

Conclusion

By taking advantage of the built-in .charCodeAt() method in JavaScript, we're able to easily create a findASCIIValue function that successfully converts characters into their corresponding ASCII values.

Here's the final, working code:

function findASCIIValue(character) {
  return character.charCodeAt(0);
}

console.log(findASCIIValue('A')); // Outputs: 65

With this function, you can find the ASCII value of any character in JavaScript.
