The catch Block

Handle errors when they occur

The catch block receives the error object. You can inspect it to understand what went wrong and respond appropriately.

try {
  JSON.parse("invalid json");
} catch (error) {
  console.log(error.name);    // "SyntaxError"
  console.log(error.message); // Parsing error details
}

The catch block only runs if an error occurs in the try block.
