Using Hooks in React

Using Hooks in React

Hooks are a new addition in React 16.8. Hooks are functions that let you “hook into” React state and lifecycle features from function components. A list of the react hooks if you want to check them all out: useState, useEffect, useContext, useReducer, useCallback, useMemo, useRef, useImperativeHandle, useLayoutEffect, useDebugValue, *custom hook

There seem to be an endless number of ways to write the same things in code, and React is no different —like writing functional components vs class components, putting your export statements before the component name or after the entire function…It’s very confusing when you’re first starting out!

Well, I’m here to show you yet another way of writing the same thing in a different way. But I promise hooks are worth the learning curve — they will make your code much cleaner and more readable.

So what are these hooks?

Hooks

Hooks allow you to use state without writing class components.

What does this even really mean for our code? There are actually several different types of hooks, and they each have their own special functionality, like making sure a component only re-renders if a certain state is changed.

Functional Components

First, let’s look at how we can change our Class components into functional components:

import React, { Component } from "react";

class Stuff extends Component {

  // state constructor would go here   render() {
    return (
      <div>

      </div>
    );
  }
}

export default Stuff

Can instead be written:

import React from "react";

const Stuff = props => (// hooks will go here    return (         <div>

       </div>
 )

export default Stuff

Alright — this makes it a little cleaner! But is it enough to make it worth learning hooks? You betcha — let’s start by looking at how the useState hook can help us with — you guessed it — using state.
