+title: Store.push()
+---
+
+The `Store.push()` method adds the parameters you pass it to the array stored under `key`.
+
+If `key` does not hold and Array, the Store will log a warning, but nothing will happen.
+
+## Signature
+
+```js
+Store store.push(mixed value1, mixed value2, ...)
+```
+
+<Note compact>This method is [variadic](https://en.wikipedia.org/wiki/Variadic_function)</Note>
+
+<Tip compact>This method is chainable as it returns the `Store` object</Tip>
+
+## Example
+
+```js
+const store = new Store()
+store.set('example', ['Hi there'])
+store.push(
+ 'How are you doing',
+ 'How are YOU doing'
+)
+```
