# Digital Toolkit vs Pencil Box

When I first started learning React, I felt like an artist deciding which tools to use. Should I stick to the **traditional toolkit** or switch to the **modern digital app**? That’s exactly what the difference between **Class Components** and **Function Components** feels like.

## The Traditional Way – Class Components

Imagine sitting at a desk, ready to draw. In front of you is a **pencil box filled with tools**: pencils, erasers, sharpeners, a ruler, maybe even a compass.

Every time you want to add detail, you reach for a different tool.

* Want to shade? Pick a pencil.
    
* Want to fix a mistake? Grab the eraser.
    
* Want a circle? Use the compass.
    

It works, no doubt. But it feels **heavy and procedural**. You’re constantly managing tools, keeping track of steps, and making sure you don’t misplace anything.

This is what **Class Components** are like in React. You get structure, built-in methods, and lifecycle hooks, but there’s more overhead. Every class component requires a **constructor** for initializing state, explicit use of `this` to access props and methods, and lifecycle methods like `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount` to manage side effects. Updating the state involves - `this.setState()`, merging the new state with the existing state in a controlled manner. While class components provide a **clear separation of concerns** and are fully capable of managing complex UI and stateful logic, they tend to be more **verbose and rigid**!

## The Modern Way – Function Components

Now, imagine opening an iPad with a stylus. Suddenly, you don’t need a separate eraser, compass, or sharpener. Everything you need—brushes, colors, undo/redo, even layers—is right there in one place.

If you want to try something new, just switch tools with a tap. No fumbling, no extra setup. It feels **lighter, faster, and modern**.

This is what **Function Components with Hooks** are like. They give you all the power of React—state, side effects, reusability—without the weight of class syntax and lifecycle methods. React has exciting hooks, which are like a great assist while coding complex logic. Function components are **lighter, more modular, and highly reusable**, making them the modern standard for building React applications.

## Which Should You Choose?

Both approaches let you create beautiful art. But while traditional tools (Class Components) still work, most artists today prefer the iPad (Function Components). They’re **simpler, more flexible, and the recommended way forward in React**.

So the next time you sit down to “draw” with React, ask yourself:  
Do you want the **pencil box** or the **digital canvas**?
