# --description--
|
|
|
|
An easy way to append data to the end of an array is via the `push()` function.
|
|
|
|
`.push()` takes one or more <dfn>parameters</dfn> and "pushes" them onto the end of the array.
|
|
|
|
Examples:
|
|
|
|
```js
|
|
var arr1 = [1,2,3];
|
|
arr1.push(4);
|
|
// arr1 is now [1,2,3,4]
|
|
|
|
var arr2 = ["Stimpson", "J", "cat"];
|
|
arr2.push(["happy", "joy"]);
|
|
// arr2 now equals ["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
|
|
var myArray = [["John", 23], ["cat", 2]];
|
|
|
|
// Only change code below this line
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
var myArray = [["John", 23], ["cat", 2]];
|
|
myArray.push(["dog",3]);
|
|
```
