--description--

An easy way to append data to the end of an array is via the push() method.

The push() method takes one or more arguments and appends them to the end of the array, in the order in which they appear. It returns the new length of the array.

Приклади:

const arr1 = [1, 2, 3];
arr1.push(4, 5);

const arr2 = ["Stimpson", "J", "cat"];
arr2.push(["happy", "joy"]);

arr1 now has the value [1, 2, 3, 4, 5] and arr2 has the value ["Stimpson", "J", "cat", ["happy", "joy"]].

--instructions--

Виштовхніть ["dog", 3] в кінець змінної myArray.

--hints--

Тепер myArray має дорівнювати [["John", 23], ["cat", 2], ["dog", 3]].

assert(
  (function (d) {
    if (
      d[2] != undefined &&
      d[0][0] == 'John' &&
      d[0][1] === 23 &&
      d[2][0] == 'dog' &&
      d[2][1] === 3 &&
      d[2].length == 2
    ) {
      return true;
    } else {
      return false;
    }
  })(myArray)
);

--seed--

--after-user-code--

(function(z){return 'myArray = ' + JSON.stringify(z);})(myArray);

--seed-contents--

// Setup
const myArray = [["John", 23], ["cat", 2]];

// Only change code below this line

--solutions--

const myArray = [["John", 23], ["cat", 2]];
myArray.push(["dog",3]);
