react hoc functional component code example

Example 1: functional component react

function Welcome(props) {
  return 
Hello, {props.name}
;
}

function App() {
  return (
    

                      
  );
}

ReactDOM.render(
  ,
  document.getElementById('root')
);

Example 2: how to pass props to higher order component

just pass your props as normal to the WrappedComponent

//App Component / root component
import React from 'react';
import WrappedComponent from "./WrappedComponent";

export default function App() {
    return (
        

            
        
    )
}
//******************************************************************************
// WrappedComponent
import React from 'react';
function WrappedComponent({}) {
    return (
        

            
Hello World
        
    )
}

export default ComponentEnhancer(WrappedComponent)
//*****************************************************************************
// higher order component called ComponentEnhancer
import React from 'react';
import PropTypes from 'prop-types';
export default (WrappedComponent) => {
    const hocComponent = ({ ...props }) => {
    		console.log(props.name)//CreatorOfCode
            return 

    hocComponent.propTypes = {};
    return hocComponent;
}

Example 3: functional components react

function Comment(props) {
  return (
    

      

        
        

          {props.author.name}
        
      
      

        {props.text}
      
      

        {formatDate(props.date)}
      
    
  );
}

Example 4: high level components react

import React, { useState } from 'react';

class WelcomeName extends React.Component {
  render() {
    return 
Hello, {this.props.name}
  }
}

function HighHookWelcome() {
  const [name ,setName] = useState("Default Name Here");
  return(
    
  );
}

// Note: Didn't need to use state for a static value.
// Minimal example, just to illustrate passing state/props.
// setName is a function to change the name value.
