Boost Your Coding Efficiency with the Ultimate Modern JavaScript Cheat Sheet!

Stop wasting time scrolling through endless documentation or Googling basic syntax—it's time to code smarter, not harder!

Imagine this is part of your daily workflow:

// Arrow functions simplified:
const add = (a, b) => a + b;
console.log(add(5, 3)); // 8

// Destructuring for clarity:
const person = { name: "Alice", age: 30 };
const { name, age } = person;
console.log(`${name} is ${age} years old`);

// Async/Await for smooth data fetching:
async function fetchData(url) {
  try {
    const res = await fetch(url);
    return await res.json();
  } catch (error) {
    console.error("Error fetching data:", error);
  }
}
