Type Script Interview question you’ll almost definitely face. I’m starting a short series about real TypeScript challenges from interviews — and we’ll begin with one of the most popular ones: implementing Pick. You’ll often get a task like this: “Recreate the Pick utility type.” The solution is below in the screenshot 👇 At first, it looks simple. But this task checks whether you really understand the fundamentals. It shows how well you understand generics, what keyof really means, how mapped types work, and how TypeScript connects keys to value types. In short, you’re creating a new type by selecting only specific properties — safely and strictly. If you can explain this clearly in an interview, you’re already ahead of many candidates.

I could use a little advice... I have a technical interview coming up that will likely focus on vanilla JavaScript. Most of my recent work has been in Next.js, React, and TypeScript, so I’m comfortable with JavaScript overall, but I want to make sure my core fundamentals are sharp going into the interview. For those of you who work closer to the language itself, what topics or concepts would you recommend brushing up on? Anything you’ve seen come up often or that made a difference in your own interviews. Appreciate any tips or suggestions.

🚀 React Interview Prep – Day 5 Today I revised one of the most commonly asked React interview topics — useState Hook⚛️ 🔹 What is `useState`? `useState` is a React Hook that allows functional components to store and manage state. Before Hooks, state was only possible in class components. Now with `useState`, functional components can also be powerful and dynamic 💪 ```js const [count, setCount] = useState(0); ``` 🔹 Why does `useState` return an ARRAY? `useState` returns an array with 2 elements: 1️⃣ Current State Value 2️⃣ Function to Update the State ```js const [count, setCount] = useState(0); ``` Here: * `count` → current value * `setCount` → function to update it React uses array destructuring to assign both easily. 🔹 How does `useState` work internally? Whenever we update the state using the setter function: ```js setCount(count + 1); ``` 👉 React: * Updates the state value * Re-renders the component * Updates only the parts of the UI where the state is used This makes React apps fast and efficient ⚡ Also, state updates are asynchronous, so React may batch multiple updates for better performance. 🔹 Using Multiple `useState` in One Component Yes! We can use multiple state variables for better readability and separation of concerns. ```js const [name, setName] = useState(""); const [age, setAge] = useState(0); const [isLoggedIn, setIsLoggedIn] = useState(false); ``` Each state is independent, which makes functional components clean and modular ✨ 📌 Interview Tip: If asked *“Why not use a single state object?”* You can say: 👉 Multiple `useState` calls make updates simpler and avoid unnecessary re-renders caused by object merging. Day 5 done ✅ Consistency > Motivation #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactHooks #100DaysOfCode #InterviewPreparation #LearningInPublic

⚛️ Most misunderstood React concept in interviews: Re-renders. Many developers think: “Re-render means the DOM updates.” Not true. A re-render means React runs your component function again. The DOM only updates - if something actually changed after reconciliation. React re-rendering isn’t the enemy. Unnecessary work is. So React developers don’t fear from re-renders. Just understand them. #ReactJS #FrontendDevelopment #JavaScript #TechInterviews #SoftwareEngineering

React JS Interview Practice – Episode 09 A simple question… but very common in React interviews: 👉 How do you change a component’s background color when it is clicked?
