loop react code example

Example 1: react for loop in render

render: function() {
  const elements = ['one', 'two', 'three'];
  return (
    <ul>
      {elements.map((value, index) => {
        return <li key={index}>{value}</li>
      })}
    </ul>
  )
}

Example 2: loop with react and react native

import React from 'react';
import './App.css';


let items=['Item 1','Item 2','Item 3','Item 4','Item 5'];
let itemList=[];
items.forEach((item,index)=>{
  itemList.push( <li key={index}>{item}</li>)
})
function App() {
  
  return (
    <>
   
      <h2>This is a simple list of items</h2>
      <ul>
        {itemList}
      </ul>
    </>
  );
}

export default App;

Example 3: react render for loop

// for loop workaround in react render
[...Array(n)].map((_, index) => <span key={index}>element {index}</span>)
