A React component is a function which returns JSX. When you use that component inside another component, the React creates an element. <Ali /> refers to element of Ali component. So, when React sees <Ali /> it gets it's JSX and internally call React.createElement with details of Ali component such as props, key and children. React.createElement creates an object which is basically description of what needs to be rendered. Then React adds that to the virtual DOM and gets added to real DOM. Tried my best to simplify this concept. Thinking of writing a blog on it. You can subscribe to my newsletter to read in-depth. link in comment. #react #javascript #frontend #programming

🚀 React Series - Day 4 Understanding useState (The Most Used React Hook) The useState hook is what allows functional components to manage data internally. It provides two things: • A state value • A function to update that value For example, a simple counter or input field is powered by useState. One key thing to remember: State should never be updated directly - always use the setter function. 👉 This ensures React knows when to re-render the UI properly. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

💡 Conditional Rendering using && in React In React, you can show something only if a condition is true using &&. 👉 Syntax: condition && <Component /> 📌 How it works: • If condition is true → element renders • If condition is false → nothing renders 📌 Example Use Cases: • Show error messages • Display notifications • Toggle UI elements • Conditional sections 📌 Why use &&? • Cleaner than ternary (for single condition) • No need for else case • Easy to read ⚡ Perfect for simple conditional UI rendering.

🚀 React Series – Day 8 Rendering Lists Efficiently in React Displaying lists of data is a common requirement - whether it’s users, products, or messages. In React, lists are usually rendered using the map() function. Each item in the list should have a unique key. This helps React identify which items have changed, been added, or removed. Using proper keys improves performance and prevents unexpected UI issues. 👉 A good practice is to use a unique ID instead of the array index whenever possible. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

🔄 JavaScript Async Evolution Callbacks → Promises → Async/Await Here's what changed and why it matters: Callbacks — the OG way. Works, but nests into chaos fast. "Callback Hell" is real. Promises — cleaner chaining with .then() and .catch(). Big improvement, still a bit verbose. Async/Await — reads like normal code. try/catch for errors. Clean, simple, everyone loves it. ✅ Remember: Async/Await is just Promises under the hood. Learn both. Still working in a Callbacks codebase?
