JavaScript Errors

The try...catch statement allows you to handle errors gracefully without stopping the script.

try {
  // Block of code to try
  adddlert("Welcome guest!");
}
catch(err) {
  // Block of code to handle errors
  console.error(err.message);
}

The throw Statement

The throw statement allows you to create a custom error.

let x = 5;
if(x < 10) throw "Too low";
