Here is a great JavaScript interview question! What the heck is a Promise doing under the hood? In JavaScript, things usually happen one after the other. It's like a checklist each item gets done before moving to the next. When a function returns a Promise, it's like making a promise to do something, like fetch data from the internet. But JavaScript doesn't wait around for the data to come back. Instead, it moves on to the next task. Now, here's where things get interesting. While JavaScript is busy doing other stuff, like running more code, the Promise is off fetching data in the background. Once the data is fetched, the Promise is fulfilled, and it has some information to share. But JavaScript needs to know when it's time to handle that information. That's where the onFulfilled part of the Promise comes in. When the Promise is fulfilled, JavaScript takes the onFulfilled code and puts it in a special queue, ready to be run. Now, async/await enters the scene. When we mark a function as async, we're telling JavaScript, "Hey, this function might take some time to finish, so don't wait up for it." And when we use the await keyword inside an async function, it's like saying, "Hold on a sec, JavaScript. I need to wait for something important before moving on." So, when JavaScript encounters an await keyword, it pauses and lets the async function do its thing. If that thing happens to be a Promise, JavaScript knows it can move on to other tasks while waiting for the Promise to resolve. Once the Promise is resolved, JavaScript picks up where it left off and continues running the code. Promises and async/await allow JavaScript to handle asynchronous tasks while keeping things organized and in order. Promises handle the background tasks, while async/await makes it easier to work with them in our code, ensuring everything happens in the right sequence.

🎯 16. Object.keys() Returns all keys. console.log(Object.keys(person)); Output: ["name","age"] 🚀 17. Object.values() Returns all values. console.log(Object.values(person)); Output: ["Deepak",25] 🔥 18. Object.entries() Returns key-value pairs. console.log(Object.entries(person)); Output: [["name","Deepak"], ["age",25]] 📦 19. Destructuring Objects Extract values easily.

const person = { name:"Deepak", age:25 };
const { name, age } = person;

⚡ 20. Spread Operator Copy objects.

const person = { name:"Deepak" };
const updated = {...person, city:"Pune" };

🎯 Real Interview Example Array of Objects

const employees = [
    { id:1, name:"John" },
    { id:2, name:"Mike" }
];
console.log(employees[0].name);

Output: John ⭐ Most Important Topics For Interviews 🔥 Arrays 🔥 Objects 🔥 map() 🔥 filter() 🔥 reduce() 🔥 Destructuring 🔥 Spread Operator 🔥 Object.keys() 🔥 Object.values() 🔥 Array of Objects 📝 Mini Practice Questions Easy: ✅ Find largest number in array, ✅ Sum all array elements, ✅ Count array length Medium: ✅ Remove duplicates, ✅ Find second largest number, ✅ Reverse array Advanced: ✅ Group objects by property, ✅ Custom map() method, ✅ Flatten nested arrays Double Tap ❤️ For More ----- 1.59 ₽ · /balance_help

🚀 JavaScript Arrays & Objects — Complete Beginner to Advanced Guide 👨‍💻 Arrays and Objects are the most commonly used data structures in JavaScript. Almost every JavaScript application uses them extensively. Examples: User data, Product lists, API responses, Dashboard data, Shopping carts 📦 PART 1: JavaScript Arrays 🧠 1. What is an Array? An array is used to store multiple values in a single variable. Example:

const fruits = ["Apple", "Mango", "Banana"];

Access Elements: console.log(fruits[0]); Output: Apple Important: Array indexing starts from 0. ⚡ 2. Creating Arrays Method 1: const numbers = [10, 20, 30]; Method 2: const numbers = new Array(10, 20, 30); 🔥 3. Array Methods push() Adds element at the end.

const arr = [1, 2];
arr.push(3);
console.log(arr);

Output: [1, 2, 3] pop() Removes last element. arr.pop(); unshift() Adds element at beginning. arr.unshift(0); shift() Removes first element. arr.shift(); 🔄 4. Loop Through Arrays for Loop

const nums = [1,2,3];
for(let i=0; i<nums.length; i++){
    console.log(nums[i]);
}

for...of

for(let num of nums){
    console.log(num);
}

🎯 5. map() Creates a new array by transforming elements. Example:

const nums = [1,2,3];
const doubled = nums.map(num => num * 2);

console.log(doubled);

Output: [2, 4, 6] 🔥 6. filter() Returns elements matching condition. Example:

const nums = [1,2,3,4,5];
const even = nums.filter(num => num % 2 === 0);
console.log(even);

Output: [2, 4] 🚀 7. reduce() Reduces array to single value. Example:

const nums = [1,2,3,4];
const sum = nums.reduce((total,num) => total + num, 0);

console.log(sum);

Output: 10 🧩 8. find() Returns first matching element.

const users = [10,20,30,40];
const result = users.find(num => num > 20);

console.log(result); 

Output: 30 📋 9. includes() Checks if value exists.

const fruits = ["Apple","Mango"];
console.log(fruits.includes("Apple"));

Output: true 🔥 10. Remove Duplicates

const nums = [1,2,2,3,3];
const unique = [...new Set(nums)];
console.log(unique);

Output: [1, 2, 3] 📦 PART 2: JavaScript Objects 🧠 11. What is an Object? An object stores data in key-value pairs. Example:

const person = {
    name: "Deepak",
    age: 25,
    city: "Bengalore"
};

⚡ 12. Access Object Properties Dot Notation: console.log(person.name); Bracket Notation: console.log(person["name"]); 🔥 13. Add New Property

person.country = "India";
console.log(person);

❌ 14. Delete Property delete person.city; 🔄 15. Loop Through Objects for...in

for(let key in person){
    console.log(key, person[key]);
}

Coding interview questions with concise answers for software roles: 1️⃣ What happens when you type a URL and hit Enter? Answer: - DNS Lookup → IP address - Browser sends HTTP/HTTPS request - Server responds with HTML/CSS/JS - Browser builds DOM, applies styles (CSSOM), runs JS - Page is rendered 2️⃣ Difference between var, let, and const? Answer: - var: function-scoped, hoisted - let: block-scoped, not hoisted - const: block-scoped, can’t be reassigned 3️⃣ Reverse a String in JavaScript

function reverseString(str) {
  return str.split('').reverse().join('');
}

4️⃣ Find the max number in an array

const max = Math.max(...arr);

5️⃣ Write a function to check if a number is prime

function isPrime(n) {
  if (n < 2) return false;
  for (let i = 2; i <= Math.sqrt(n); i++) {
    if (n % i === 0) return false;
  }
  return true;
}

6️⃣ What is closure in JavaScript? Answer: A function that remembers variables from its outer scope even after the outer function has returned. 7️⃣ What is event delegation? Answer: Attaching a single event listener to a parent element to manage events on its children using event.target. 8️⃣ Difference between == and === Answer: - == checks value (with type coercion) - === checks value + type (strict comparison) 9️⃣ What is the Virtual DOM? Answer: A lightweight copy of the real DOM used in React. React updates the virtual DOM first and then applies only the changes to the real DOM for efficiency. 🔟 Write code to remove duplicates from an array

const uniqueArr = [...new Set(arr)];
