🚀 10 JavaScript Interview Questions Every Developer Should Know While preparing for frontend interviews, I noticed one thing: Most companies don’t ask very advanced JavaScript. They ask simple-looking questions that test how well you understand the basics. Here are some of the most common JavaScript interview questions: 1️⃣ What is the difference between var, let, and const? 2️⃣ What is the difference between == and === ? 3️⃣ What is a closure in JavaScript? 4️⃣ What is hoisting? 5️⃣ What is the difference between null and undefined? 6️⃣ What is the difference between synchronous and asynchronous code? 7️⃣ What is the event loop in JavaScript? 8️⃣ What is the difference between map(), filter(), and reduce()? 9️⃣ What is the difference between function declaration and arrow function? 🔟 What is the difference between call(), apply(), and bind()? The interesting thing is: These questions look simple. But in interviews, companies usually ask deeper follow-up questions after them. Because they want to know: > Do you only know the answer…   > Or do you really understand JavaScript? 💬 Which JavaScript question do you find the most difficult? #JavaScript #webdevelopment #frontend #developers #interviewquestions #coding #learning

🚀 Frontend Developer Interview Preparation – Day 2 Today in my preparation journey for Frontend Developer interviews, I focused on some fundamental JavaScript concepts that every developer should clearly understand. 📌 Topics I learned today: 🔹 Hoisting in JavaScript – Understanding how JavaScript moves variable and function declarations to the top of their scope during the compilation phase. 🔹 Functions & Execution Context – Learning how functions are created, stored in memory, and executed by the JavaScript engine. 🔹 The window Object – Exploring how the global object works in browsers and how variables/functions become part of the global scope. 🔹 undefined vs not defined – undefined: A variable is declared but has not been assigned a value yet. not defined: A variable was never declared in the program. These concepts helped me better understand how JavaScript actually executes code behind the scenes, which is extremely important for writing clean and bug-free applications. 🎥 Currently learning from the “Namaste JavaScript” playlist by Akshay Saini, which explains JavaScript concepts in a very deep and practical way. Highly recommended for anyone who wants to master JavaScript. If you are also preparing for Frontend Developer interviews, feel free to connect and join this learning journey with me.
