# Creating The Tiles From JavaScript What we'll do is take the list of tiles declared in the .slint language, duplicate it, and shuffle it. We'll do so by accessing the `memory_tiles` property through the JavaScript code - in our case `memory_tiles`. Since `memory_tiles` is an array in the `.slint` language, it's represented as a JavaScript [`Array`](https://slint.dev/docs/node/). We can't modify the model generated by the .slint, but we can extract the tiles from it, and put it in a [`slint.ArrayModel`](https://slint.dev/docs/node/classes/arraymodel.html) which implements the [`Model`](https://slint.dev/docs/node/interfaces/model.html) interface. `ArrayModel` allows us to make modifications and we can use it to replace the static generated model. We modify `main.js` like so: ```js {{#include main_tiles_from_js.js:main}} ``` Running this gives us a window on the screen that now shows a 4 by 4 grid of rectangles, which can show or obscure the icons when clicking. There's only one last aspect missing now, the rules for the game.
