Array copy code example

Example 1: java array copy

// Shallow copy
int[] src = {1,2,3,4,5};
int[] dst = Arrays.copyOf(src, src.length);

// Deep copy
int[] dst2 = new int[src.length];
for(int i = 0; i < src.length; i++){
	dst2[i] = src[i];
}

Example 2: copy array javascript

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

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

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

Example 3: java copy array

int[] a = {1,2,3,4,5};
int[] b = Arrays.copyOf(a, a.length);

Example 4: js array clone

let clone = [...myArray]

Example 5: javascript copy array

var numbers = [1,2,3,4,5];
var newNumbers = Object.assign([], numbers);

Example 6: javascript copy array

/* 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"]
