Error Handling in JavaScript - #38 @Everyday-Be-Coding

Error handling in JavaScript is crucial for writing robust and reliable code. JavaScript provides several mechanisms for handling errors and exceptions. Here's an overview:

Try...Catch Statement: The try...catch statement allows you to catch and handle exceptions that occur within a block of code.

JavaScript code:
try {
// Code that may throw an exception
throw new Error("Something went wrong");
} catch (error) {
// Handle the exception
}

Throw Statement: You can throw your own exceptions using the throw statement. This is useful for signaling errors or exceptional conditions in your code.

JavaScript code:
function divide(a, b) {
if (b === 0) {
throw new Error("Division by zero");
}
return a / b;
}
Error Object: JavaScript provides built-in error objects like Error, SyntaxError, ReferenceError, TypeError, etc., which can be thrown or caught.

JavaScript code:
try {
// Code that may throw a TypeError
} catch (error) {
if (error instanceof TypeError) {
} else {
}
}

Finally Block: You can use the finally block to execute code regardless of whether an exception is thrown or not. This block is optional and follows the catch block.

JavaScript code:
try {
// Code that may throw an exception
throw new Error("Something went wrong");
} catch (error) {
// Handle the exception
} finally {
// Code that always runs
}

By using these error handling techniques effectively, you can make your JavaScript code more resilient and easier to debug.
