Everyone writes bugs. Being a good developer means being good at finding and fixing them.

Console Tricks

The Debugger Keyword

If you put debugger; in your code, the browser will pause execution at that line (if DevTools is open), allowing you to inspect variables step-by-step.

function trickyLogic(x) {
  let y = x * 2;
  debugger; // Browser will pause here!
  return y + 1;
}
