function tamanhoNomeCompleto(a,b){
  var tNC = a.length + " ".length + b.length;
  return tNC;
}

tamanhoNomeCompleto("Paulo","Paulada");

How do I put the tNC in the return?

'Cause I’m getting this:

tamanhoNomeCompleto uses unnecessary local variables you can return the expression directly

javascript return

That?

function tamanhoNomeCompleto(a, b){
    return a.length + b.length + 1;
}

console.log(tamanhoNomeCompleto("Paulo", "Paulada"));

I put in the Github for future reference.

To variable is totally unnecessary there so just carry the expression to the return.

Variables are meant to store values, if you don’t need to save, don’t create one, use the value you’re storing in it directly where you need it.

Note that I didn’t get the size of the space because it is known (I don’t know if all browsers or Node would optimize this.

  • Thanks a lot friend, I was going crazy to figure out how to do this in Return, because I’m learning and I get really pissed when I can’t find the answer to my problem. And you taught how I use console.log for a function I couldn’t see!
