Summary  
Describes how to instantiate and use the JavaScript Error object, including retrieving its message and stack trace properties for diagnosing runtime issues.

General domain of usage  
Error handling and debugging

The `Error` object in JavaScript is a built-in object that represents runtime errors. When you create an `Error` using `new Error("message")`, you provide a descriptive string that is stored in the `message` property. This helps you understand what went wrong when reading logs or debugging code. The `stack` property contains a stack trace that shows the exact sequence of function calls leading up to the creation of the error. This information is essential for tracking down the source of bugs and understanding the flow of your program when an error occurs. By examining both the `message` and `stack` properties, you gain valuable insights into the context of errors, making it easier to debug and maintain your JavaScript code.

// Creating a new Error object
const error = new Error("Something went wrong!");

// Accessing the message property
console.log(error.message); // Output: Something went wrong!

// Accessing the stack property
console.log(error.stack); // Output: stack trace showing where the error was created

Which properties of the JavaScript `Error` object help you understand what went wrong and where the error occurred?

Master the art of detecting, handling, and debugging errors in JavaScript. Handle both synchronous and asynchronous failures using try...catch, promises, and async functions. Customize error types, apply debugging strategies, and write resilient, production-quality code that gracefully recovers from unexpected issues.

Explore how JavaScript errors occur and how to handle them effectively in synchronous code. Identify common error types, apply try and catch blocks, and use finally for cleanup to keep programs stable and predictable.

Take control of error behavior by defining, throwing, and customizing errors. Work with the JavaScript Error object, extend it to create custom types, and manage errors in both promises and async functions for cleaner, more reliable code.

Strengthen code reliability through effective debugging and best practices. Recognize common pitfalls in asynchronous error handling, apply structured debugging techniques, and build robust error management strategies for production-ready JavaScript.
