Generating random string of specified length in JavaScript

We are required to write a JavaScript function that takes in a number n and returns a random string of length n containing no other than the 26 English lowercase alphabets.

Therefore, let's write the code for this function ?

Example

The code for this will be ?

const num = 8;
const randomNameGenerator = num => {
    let res = '';
    for(let i = 0; i 

Output

The output in the console will be ?

Note ? This is one of many possible outputs. Console output is expected to differ every time.

How It Works

The function uses Math.random() to generate random numbers between 0 and 25, then converts them to lowercase letters using String.fromCharCode(97 + random), where 97 is the ASCII code for 'a'.

Alternative Method Using Array

Here's another approach using an array of characters:

const generateRandomString = (length) => {
    const chars = 'abcdefghijklmnopqrstuvwxyz';
    let result = '';
    
    for (let i = 0; i

Conclusion

Both methods effectively generate random lowercase strings. The ASCII approach is more compact, while the character array method is more readable and easier to modify for different character sets.
