array destructuring.js

'use strict';

// the idea  of destructuring is to take an object or an Array and convert it into
// smaller objects/elements/variables
// array destructuring
// console.log('----------------Array destructuring---------------------');
// const alphabet= ['A','B','C','D','E','F'];
// const numbers = ['1','2','3','4','5','6'];

// // old way
// // const a = alphabet[0];
// // const b = alphabet[1];

// // destructuring
// // if we want the rest of the elemnt we use the spread operator ...

// const [a,,c,...rest] = alphabet;
// const newArray = [...alphabet, ...numbers];

// console.log(a,c);
// console.log(rest);
// console.log(newArray);

// function sumAndMultiply(a,b){
//     return [a+b, a*b, a/b];
// }

// // const arr = sumAndMultiply(2,3);
// const [sum, multiply, division = 'No division'] = sumAndMultiply(2,3);
// console.log(sum);
// console.log(multiply);
// console.log(division);
