As in other programming languages, I just want to be clear that these are examples of recursive logic?

inside of another function: window.setTimeOut()
.
A recursive function is something like:
let recursiveFunction = (n) => {
//stop condition
if(n === 1 || n === 2){
return 1;
}
//call
return recursiveFunction (n - 2) + recursiveFunction (n - 1);
}
for(let i = 1; i < 20; i ++){
document.write("<p>fib(" + i +"): " + recursiveFunction(i) + "</p>");
}
This writes out all the fibonacci numbers from 1 to 20.

{
try
{
return recurse(depth + 1);
}
catch(ex)
{
return depth;
}
}
var maxRecursion = recurse(1);
document.write("Recursion depth on this system is " + maxRecursion);
Have fun :D

9,392 PointsAhhh.. sweet clarity. Thanks so much, I guess I'm confusing the 'calling within' technique with the iteration calling itself repeatedly, although the concepts seem may seem somewhat connnected, they are fundamentally different! Thanks

I thought you wanted just an example of recursion. I should not answer questions when I am out of time

Tim Morgan
9,392 PointsNaw, it's still good - I am trying to get past being stuck in the concepts, and just apply the programming logic. It's 'easy' but it's complicated to sort through sometimes, anyway I tried your example, and it helps a lot!
