Simplified HOC's and RenderProps in React

In React, HOCS and Render Props have common goals but different implementations. The main purpose of a higher-order component in React is to share common functionality between components without repeating code. And Render Prop is also a technique for sharing code between React components using a prop whose value is a function.

Here are the definition and screenshots below.

HOC's

HOC is an advanced technique for reusing component logic. It is a function that takes a component and returns a new component.

RenderProps

A component with a render prop takes a function that returns a React element and calls it instead of implementing its own render logic

#App.js

import React from "react";
import "./style.css";
import Welcome from './Welcome';
import Location from './Location';

export default function App() {
  return (
    <div>
      <h2 style={{color: "red"}}>Highorder example</h2>
      <Welcome/>
      ---------------------------------------------
      <h2 style={{color: "red"}}>RenderProps example</h2>
      <Location/>
    </div>
  );
}


#Hoc.js

import React from 'react';
import ReactDOM from 'react-dom';

function Hoc(Component) {
  const user = 'Hi User';

  return function () {
    return <Component user={user} />
  };
}

export default Hoc;

#Welcome.js

import React from 'react';
import MyHoc from "./HocExample";

const Welcome = ({ user }) => {
  return (
    <>
      <h1> {user} </h1>
      <h1 style={{ color: "green" }}>Welcome to CDK Global</h1>
    </>
  );
}
export default MyHoc(Welcome);

#RenderPropExample.js

import React from 'react';
import ReactDOM from 'react-dom';

function RenderPropExample(props) {
  const city = "Hyderabad";
  const location = <h1>Location</h1>

  return props.children({
    location: location,
    city: city

  })
}
export default RenderPropExample;


#Location

import React from 'react';
import Renderprop from "./RenderPropExample";

const Location = () => {
  return (
    <>
     <Renderprop>
        {({ location, city }) => {
          return (
            <>
            <h3>{location} </h3>
            <h1 style={{ color: "green" }}>{city} </h1>
            </>
          )
        }
        }
      </Renderprop>
    </>
  );
}
export default Location;
