typescript get part of array code example

Example 1: js copy part of array

// The slice function copies parts of an array and 
// do therefore not change the default array

let arr = ["apple", "kiwi", "banana", "pear"];

let newArray = arr.slice(1, 2)

console.log(newArray); // output : kiwi

Example 2: return last two values of array in javascript

var arr1 = [0, 1, 2, 3, 4, 5, 6, 7],
  arr2 = [0, 1, 2, 3];

document.body.innerHTML = 'ARRAY 1: ' + arr1.slice(1).slice(-5) + '<br/>ARRAY 2: ' + arr2.slice(1).slice(-5);
