extmple.js” is used to test both standard and custom error handling.

**Requirement 1: Correct JavaScript Syntax and Error Handling**

* Fix any syntax errors in the provided JavaScript code. This includes missing semicolons, incorrect variable declarations, and typos. Ensure that the code correctly handles both `try…catch` blocks and uses appropriate error objects.
* Implement robust error handling throughout the code to catch potential exceptions and provide informative error messages to the user.
* Include specific error handling for the following scenarios:
* Invalid input data (e.g., non-numeric input when a number is expected).
* Network errors when fetching data (e.g., problems with the `fetch` API).
* Unexpected errors within the code. A generic error handler should be included.

**Requirement 2: Functionality and User Interaction**

* The script must include at least three distinct functions.
* The script must take user input using a `prompt()` or `confirm()` to initiate operations.
* Provide a simple user interface with `alert()` or `console.log()` to show output.
* The script should do the following:
1. Prompt the user for a number.
2. Fetch data from a publicly available JSON API (e.g., `https://jsonplaceholder.typicode.com/todos/1`).
3. Perform a calculation using the number provided by the user and the data fetched from the API.
4. Display the result.

**Requirement 3: Code Readability and Style**

* Use meaningful variable and function names.
* Add comments to explain the purpose of each function and the logic within the code.
* Format the code consistently with proper indentation.

**Requirement 4: Error Message Specificity**

* The error messages must be specific and inform the user what went wrong and, if possible, how to fix it.

**Example:**

“`javascript
// Function to fetch data from a JSON API
async function fetchData(url) {
try {
const response = await fetch(url);
if (!response.ok) {
throw new Error(`HTTP error! Status: ${response.status}`);
}
const data = await response.json();
return data;
} catch (error) {
console.error(“Error fetching data:”, error);
alert(“An error occurred while fetching data. Please check your network connection or the URL.”);
return null;
}
}

// Function to perform a calculation
function calculate(userNumber, apiData) {
if (typeof userNumber !== ‘number’ || isNaN(userNumber)) {
throw new Error(‘Invalid input: Please enter a valid number.’);
}
if (!apiData) {
throw new Error(“API data is missing. Cannot perform calculation.”);
}
// Perform a sample calculation
const result = userNumber * apiData.id;
return result;
}

// Main function to orchestrate the process
async function main() {
try {
const userNumber = parseFloat(prompt(“Please enter a number:”));
const apiData = await fetchData(‘https://jsonplaceholder.typicode.com/todos/1’);

if (!apiData) {
return; // Exit if data fetching failed
}

const calculationResult = calculate(userNumber, apiData);
alert(`The result of the calculation is: ${calculationResult}`);
} catch (error) {
console.error(“An unexpected error occurred:”, error);
alert(error.message || “An unexpected error occurred. Please try again later.”);
}
}

// Start the process
main();
“`

**Your Task:**

Create a complete and functional `example.js` file that meets all the requirements above. The javascript code should be inside `
