console.log(); is extremely useful to help you find out where a program isn't executing, or to give you a status.

You don't HAVE to log your program, yet, if your function syntax is wrong or your statements are wrong and there are no log methods within, you could have a hard time figuring out WHY your function isn't working.

console.log("Booted up...");
var g = false;

function run(a,b) {
  console.log("Stage 1. Testing Condition if a is less than b");
  if (a < b) {
    if (g === true) {
        console.log("Stage 1 successful. This conditional statement is operational");
        return a;
  } else if (a > b) {
     console.log("Stage 1 unsuccessful. " + a + " is greater than " + b ".");

Just squeezed that example out, may have some syntax errors, shrug. The intent is to show how logging to the console can keep you updated on what is going on.
