Hello,

I am learning Javascript and TypeScript and got to the Recursion section of my course.

Now, I have this exercise, where I need to write a recursive function for changing specific characters into a different character.

Here is my code so far:

JavaScript
'use strict'

function strings1(str:string):any{
    try {
        let newStr:string = "";
        let changed = str.split('');
        console.log(str);        
        if (newStr == "") {
            changed.splice((changed.indexOf('x')), 1, "y");
            newStr += changed.join("");
        }
        return newStr;
    }
    catch (error)
    {
        console.log(error);
    }
}


What I have tried:

I tried to call the function inside a while loop, but that's not the solution.
I looked at the length of the input string then tried with charAt() and replace().
I have no idea how to write this recursively.

Recursion is when a function repeatedly calls itself with a modified form of its input parameter. See javascript recursion - Google Search[^].
