Arrow Functions vs Regular Functions in React

What are the main differences between arrow functions and regular functions in React?

Arrow functions in React are lexically bound to the context they are defined in, while regular functions have their own context. This means that arrow functions do not require binding 'this' when used as event handlers.

Can you give me an example of when to use an arrow function?

Sure! If you're passing a function as a prop to a child component, using an arrow function can help maintain the correct 'this' context.

Are there any performance implications of using one over the other?

Yes, using arrow functions can lead to performance issues if they are defined inside render methods, as they create a new instance on each render. Regular functions can be defined outside to avoid this.

What about readability? Which one is more readable?

Arrow functions are often more concise and can improve readability, especially for short functions. However, regular functions can be clearer for more complex logic.
