JavaScript: Modern Async/Await & Fetch API

Master asynchronous JavaScript using modern async/await syntax to fetch remote JSON data cleanly with try/catch error handling.

JavaScript Async/Await & Fetch API

Modern JavaScript handles asynchronous operations with sync functions and the wait operator, making asynchronous code look and behave like synchronous code.

Syntax

javascript

async function loadData() {

  try {

    const res = await fetch(url);

    const data = await res.json();

    return data;

  } catch (err) {

    console.error(err);

  }

}

Your Task

Write an async function called calculateToolMetrics(tools) that filters tools with a rating of 4.5 or higher and returns their total count.

Target Output

Need a Hint?

Use the .filter() method on tools array
Condition is t.rating >= 4.5
Return .length of the filtered array
