--description--

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

.push() takes one or more parameters and "pushes" them onto the end of the array.

Examples:

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

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

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

--instructions--

Push ["dog", 3] onto the end of the myArray variable.

--hints--

myArray should now equal [["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]);
