Recursive string reversal function in javascript?

Question

I\'m a pretty experienced frontend engineer with a weak CS background. I\'m trying to get my head around the concept of recursion. Most of the examples and purported explana

Answer 1

It is verbose, but I like making it easy to understand in logical steps:

function rev(soFar, count){
   console.log("asString: " + soFar );
   console.log("count: " + count);
   var len = soFar.length;
   var ret = soFar;//ret needs to be a reference to soFar
   if(len > count){
      var subd = soFar.substring(1,len);
      var first = soFar[0];
      //we want to inject the first letter at the index position one back from the length, minus what the count is at this point
      var indexOfInsert = len-1 - count;//so if count is 0 and length is 5, we want 4 (4 -0)
      var asArray = subd.split("");
      asArray.splice(indexOfInsert,0,first);
      count++;//need to increment count for the next round
      var asString = "";
    //recreate as string, not array - the default toString() makes this a comma delimited string. It is best toi just recreate it in a loop
    for(var i = 0; i

}

Then call it like:

var reversed = rev("Hello",0);
console.log("result",reversed);
