If you want to learn JavaScript within one our, then this course is not for you.
Hello, friend.
Welcome to my complete JavaScript Bootcamp project course.In this course, you learn our most popular programming language JavaScript from basic to advanced level.Every topic is step by step with live example.These JavaScript goals is totally different from existing all JavaScript related courses because I have
designed this course like that way, you will learn almost every functionality of JavaScript from basic to advanced by building multiple real life projects, so it will help you to learn JavaScript more effectively.
In his course, you will not only learn JavaScript, you will learn
RESTful API creation,
Node.js Reactors,
Express, JS,
MongoDB and much more.
============ IN THIS VIDEO YOU WILL LEARN JAVASCRIPT ERROR HANDLING METHODS =========================
📺 Error Handlings in JavaScript :-
➽ Error Object: JavaScript has a built-in Error object that represents an error condition. It contains information about the error, such as a message and a stack trace.
➽ try...catch Statement: The try...catch statement is used to handle exceptions (runtime errors) within a block of code. Code that might throw an exception is placed inside the try block, and the handling logic is in the catch block.
➽ throw Statement: The throw statement is used to create a custom error or to throw an exception. It is often used in combination with the try...catch statement.
➽ Error Types: Besides the generic Error object, JavaScript has several built-in error types such as SyntaxError, ReferenceError, TypeError, etc., each representing a specific category of error.
➽ Custom Errors: Developers can create custom error types by extending the Error object. This allows for more specific error handling in applications.
➽ finally Block: The finally block is used with the try...catch statement and contains code that will be executed regardless of whether an exception was thrown or caught.
➽ Unhandled Rejections: In asynchronous code using promises, unhandled rejections can be captured using the unhandledrejection event. This event allows handling asynchronous errors globally.
➽ Window.onerror Event Handler: In a browser environment, the window.onerror event handler can be used to capture unhandled exceptions globally.
➽ Async/Await Error Handling: When using async/await syntax for asynchronous programming, errors can be caught using try...catch blocks around await expressions.
➽ Error Propagation: Errors can be propagated up the call stack by not catching them at a lower level, allowing higher-level code to handle them.
➽ Error Stack Trace: The stack trace, available in the stack property of an Error object, provides information about the call stack at the time the error occurred. It helps in debugging by showing the sequence of function calls.
