1. Arrow Functions: Your New Best Friend
Remember the days of binding this everywhere? Say goodbye to that headache! Arrow functions are here to save the day.
Instead of this verbose mess:
<button onClick={this.handleClick.bind(this)}>Click Me!</button>
Try this sleek one-liner:
<button onClick={() => this.handleClick()}>Click Me!</button>
It's like magic, right? Your event handlers just got a whole lot sexier! š
2. Conditional Rendering: The && Magic
Want to show something only when a condition is true? Forget those bulky if statements. The && operator is your new secret weapon.
Old school:
{isLoggedIn ? <WelcomeBack /> : null}
New hotness:
{isLoggedIn && <WelcomeBack />}
Clean, simple, and straight to the point. Your code just lost weight and gained clarity!
3. Destructuring: Unpacking Goodness
Tired of typing this.props a million times? Destructuring to the rescue! It's like unpacking a suitcase of goodies.
Before:
const name = this.props.name;
const age = this.props.age;
After:
const { name, age } = this.props;
Boom! Less typing, more coding. Your wrists will thank you later.
4. Fragment Shorthand: Less is More
Need to group elements without adding extra DOM nodes? Fragments are your friend, and their shorthand is even friendlier.
The old way:
<React.Fragment>
<Header />
<Main />
<Footer />
</React.Fragment>
The new way:
<>
<Header />
<Main />
<Footer />
</>
It's like your code went on a diet and lost all that extra weight!
5. Spread Attributes: Props Made Easy
Passing a ton of props? Spread them like butter on hot toast!
Instead of this finger workout:
<MyComponent prop1={props.prop1} prop2={props.prop2} prop3={props.prop3} />
Just spread it:
<MyComponent {...props} />
Less typing, fewer errors, and your code looks as smooth as silk.
6. Function Components: The Arrow Way
Function components are cool, but arrow function components? They're ice cold!
Old school:
function Welcome(props) {
return <h1>Hello, {props.name}</h1>;
}
New school:
const Welcome = ({ name }) => <h1>Hello, {name}</h1>;
Short, sweet, and modern. It's like your components got a hip new makeover!
7. Optional Chaining: Safe Property Access
Tired of checking if every single property exists? Optional chaining is like a safety net for your object properties.
The cautious way:
const userName = user && user.info && user.info.name;
The confident way:
const userName = user?.info?.name;
It's like having a bodyguard for your properties. No more undefined errors sneaking up on you!
8. State Initialization: No Constructor Needed
Initialize your state without the constructor ceremony. It's state declaration made simple!
Old fashioned:
constructor(props) {
super(props);
this.state = { count: 0 };
}
New and improved:
state = { count: 0 };
Less code, same result. It's like skipping the small talk and getting straight to the point!

Be careful using conditional rendering with &&
Your thoughts on this please!!
Please note that most/all of these features are JavaScript features and not specific to React.
Those are good tips, generally those are js tips not react, and functional components may have more easy and explicit syntax than classes, no body need to use classes anymore
this.handleCallback, no one nowadays use class components.
