🚀 Day 4 of Learning React: What Actually Makes React... React? (Hooks, useState, and State Explained)

Short summary

In Day 4 of this React learning journey, discover that Hooks—specifically useState()—are what enable components to remember state between renders. Learn how useState() returns both current state and a setter function, and how calling the setter automatically triggers re-renders only when values change. The post also clarifies default vs named exports in JavaScript modules with practical code examples.

• •useState() returns an array with current state and a setter function
• •Calling the setter triggers re-renders only when the value actually changes
• •Default exports can use any name; named exports require braces and preserve their names
