How to Handle Errors in JavaScript ?

Handling errors in JavaScript is crucial for writing robust and reliable code. There are several mechanisms and best practices for error handling in JavaScript:

• Try…Catch Statement:
  • Use the try...catch statement to catch and handle exceptions. Code inside the try block is executed, and if an exception occurs, it’s caught and handled in the catch block.
• Throw Statement:
  • You can throw your own custom errors or exceptions using the throw statement.
• Finally Block:
  • The finally block is optional and is executed regardless of whether an exception is thrown or not.
• Error Object:
  • The Error object contains information about the error, such as the error message (message property) and the name of the error (name property).
• Global Error Handling:
  • You can set up a global error handler using the window.onerror event to catch unhandled exceptions globally.
• Promises:
  • When working with asynchronous code using promises, you can use the .catch() method to handle errors.
