Example 1: copy array javascript

const sheeps = ['Apple', 'Banana', 'Juice'];

// Old way
const cloneSheeps = sheeps.slice();

// ES6 way
const cloneSheepsES6 = [...sheeps];

Example 2: copy one array to another javascript

/* Copying arrays or parts of arrays in JavaScript */

var fruit = ["apple", "banana", "fig"]; // Define initial array.
console.log(fruit); // ["apple", "banana", "fig"]

// Copy an entire array using .slice()
var fruit2 = fruit.slice(); 
console.log(fruit2); // ["apple", "banana", "fig"]

// Copy only two array indicies rather than all three
// From index 0 (inclusive) to index 2 (noninclusive)
var fruit3 = fruit.slice(0,2); 
console.log(fruit3); // ["apple", "banana"]
