Example 1: 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 (
        <div>
            <WrappedComponent name="CreatorOfCode" />
        </div>
    )
}
//******************************************************************************
// WrappedComponent
import React from 'react';
function WrappedComponent({}) {
    return (
        <div>
            <h1>Hello World</h1>
        </div>
    )
}

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 <WrappedComponent {...props} 
    	}/>

    hocComponent.propTypes = {};
    return hocComponent;
}

Example 2: high level components react

import React, { useState } from 'react';

class WelcomeName extends React.Component {
  render() {
    return <h1>Hello, {this.props.name}</h1>
  }
}

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

// 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.
