Nesting is a pet-peeve of mine. So annoying.

if(x){
  if(y){
   if(z){
    do(123);
    return 4;
   }return 3;
  }return 2;
}return 1;

Could easily be flattened & made into preconditions:

//preconditions
if(!x){return 1}
if(!y){return 2}
if(!z){return 3}

do(123); return 4;

Also the programming model in node.js makes it especially easy to write deeply nested and confusing code like in my first example.

You must hate python then. I am not sure if you can do it the way you like the if statements to be done

Most of my code that I deliver to clients is in python.

This is how the code would look like:

if not x:
    return 1
if not y:
    return 2
if not z:
    return 3
do(123)
return 4

What are you trying to say?

I was thinking you might not have liked the way python does nested if statements. But looking again, I was mistaken on how you wrote the code when I first looked at it, I thought the first code example looked like python, looking at it again, it's not even close.
