海外TECH	DEV Community	Understanding react hook(Part:1)-useState()	https://dev.to/srishtikprasad/understanding-react-hookpart1-usestate-5he1	Understanding react hook Part useState What are React Hooks and why do we need it Hooks are functions that let you “hook into react state of a function and modify it Hooks don t work inside classes they let you use React without classes It is a way of being able to make our web page interactive that have changeable state make the website more interactive There are three basic hook useState useEffect useContext In this part I ve covered useState hook If someone ask to write a function to increment count by clicking on button and show changes on screen that is on client side import React from react import ReactDOM from react dom let count function increase count ReactDOM render lt div className container gt lt h gt count lt h gt lt button onClick increase gt lt button gt lt div gt document getElementById root According to the above code clicking button value on the screen should increase But it is not so because they are not real HTML elements instead react is rendering it So to update count on screen we have to re render it import React from react import ReactDOM from react dom let count function increase count ReactDOM render lt div className container gt lt h gt count lt h gt lt button onClick increase gt lt button gt lt div gt document getElementById root ReactDOM render lt div className container gt lt h gt count lt h gt lt button onClick increase gt lt button gt lt div gt document getElementById root How useState hook works Const state setState useState initialState useState gives us back two parameters inside of an array Use array destructuring to declare in this order state value and the function that will modify that state value You can name these two items whatever you want useState hook returns a stateful value and a function to update it During the initial render the returned state is the same as the value passed as the first argument initialState The setState function is used to update the state It accepts a new state value and add re render of the component During subsequent re renders the first value returned by useState will always be the most recent state after applying updates Re iterating the above code with hook will yield the required effect without having to write a number of lines of code and So to solve the problem of re rendering it we use useState hook here import React useState from react function App const count setCount useState function increase setCount count return lt div className container gt lt h gt count lt h gt lt button onClick increase gt lt button gt lt div gt Both the left and right sides of the code will produce the same result Just to highlight how useful hooks are here s a comparison	2022-06-12 10:45:24
