ES6 Spread operator in javascript

 Spread Operator

Spread syntax allows arrays and objects to be expanded into :

- elements in case of array.
- key-value pairs in case of object.


ES6 is different version of the ECMAScript specification. Which is the standard that defines the scripting language that javascript is based on.

ES6 release on 2015 and there are so many features Arrow function, classes, let and const for variables.


For use copy iterable object (...) allows is to quickly copy all or part of an existing array or object into another array or object.

Actually we have used this code in reactjs called as TheArrow.jsx

Example

import React from 'react'

function TheSpread() {

    let myarr1 = [1, 2, 3, 4, 5, 6];
    let myarr2 = [7, 8, 9, 10, 11, 12];
    let myarr3 = [...myarr1, ...myarr2];

    console.log(myarr3);


  
  return (
    <div>
    
    <h1>Check Console</h1>
    
    
    </div>
  )
}

export default TheSpread
