Activity 1: Basic Error Handling with Try-Catch

• Task 1: Write a function that intentionally throws an error and use a try-catch block to handle the error and log an appropriate message to the console.

• Task 2: Create a function that divides two numbers and throws an error if the denominator is zero. Use a try-catch block to handle this error.

Activity 2: Finally Block

• Task 3: Write a script that includes a try-catch block and a finally block, Log messages in the try, catch, and finally blocks to observe the execution flow.

Activity 3: Custom Error Objects

• Task 4: Create a custom error class that extends the built-in Error class, Throw an instance of this custom error in a function and handle it using a try-catch block

• Task 5: Write a function that validates user input (e.g., checking if a string is not empty) and throws a custom error if the validation fails. Handle the custom error using a try-catch block.

Activity 4: Error Handling in Promises

• Task 6: Create a promise that randomly resolves or rejects. Use .catch() to handle the rejection and ing an appropriate message to the console.

• Task 7: Use try-catch within an async function to handle errors from a promise that randomly resolves or rejects, and log the error message.

Activity 5: Graceful Error Handling in Fetch

• Task 8: Use the fetch API to request data from an invalid URL and handle the error using catch() Log an appropriate error message to the console.

• Task 9: Use the fetch API to request data from an invalid URL within an async function and handle the error using try-catch. Log an appropriate error message.

1. Basic Error Handling Script: Write a script that demonstrates basic error handling using try-catch and finally blocks.

2. Custom Error Script: Create a script that defines and throws custom error, handling them with try-catch blocks.

3. Promise Error Handling Script: Write a script that handles errors in promises using .catch() and try-catch within async functions.

4. Fetch Error Handling Script: Create a script that handles errors when using the fetch API to request data from invalid URLs.

By the end of these activities, you will:

• Understand and implement basic error handling using try-catch blocks.

• Use finally blocks to execute code regardless of the try-catch outcome.

• Create and use custom error classes.

• Handle errors in promises using .catch() and within async functions using try-catch.

• Implement graceful error handling when making network requests with the fetch API.
