Welcome back to the MERN Stack Full Course Bangla playlist! Today is Day-21, and this is React Class – Part 2, where we focus on one of the most important React concepts — state.

In this class, you’ll learn how state works in class components, how to update state properly using setState(), and how to handle user input by storing form values inside state. These concepts are essential for building dynamic and interactive React applications.

We’ll go step-by-step with clear examples so you understand how data flows inside a React component and how UI updates automatically when state changes. This lesson builds the foundation for events, forms, and advanced React logic.

By the end of this video, you’ll be comfortable managing state in class components and ready to move forward with confidence.
