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. Examples: ```js 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-- Push `["dog", 3]` onto the end of the `myArray` variable. # --hints-- `myArray` should now equal `[["John", 23], ["cat", 2], ["dog", 3]]`. ```js 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-- ```js (function(z){return 'myArray = ' + JSON.stringify(z);})(myArray); ``` ## --seed-contents-- ```js // Setup const myArray = [["John", 23], ["cat", 2]]; // Only change code below this line ``` # --solutions-- ```js const myArray = [["John", 23], ["cat", 2]]; myArray.push(["dog",3]); ```
