# Create an E-Commerce product search page clone (Part 1): List ## Problem Statement Given a list of products create a basic HTML page that can render the products as a list of cards. Iterate over the given list to render the item card inside of a parent component identified by `id="root"`. Some basic CSS classes & JavaScript function declarations are provided as a starting point for this assignment. You would have to implement the following functions: ``` createProductCard renderAllCards ``` ## Implementation guidelines: Try to start with the renderAllCards function and inside of it first find the element with `id="root"` using `document.querySelector`. The `renderAllCards` function should take the list of items as an argument (**NOTE**: referring to the global variable inside this function might cause your submission to fail). Once you’ve selected the root element and the list of items as a parameter, now it’s time to iterate through the list to create the individual cards. Call the `createProductCard` function to get back a DOM element which can be appended to the root element as a child. The createProductCard function will accept a parameter of type object with the following structure: ```javascript { "id": 1, "name": "PlayStation 5", "description": "....", "image": "....", "price": 400, "memory": "8 GB", "storage": "1 TB", "colors": ['black', 'white', 'blue'] } ``` You’re expected to return a DOM element i.e. the card component for the given payload. - The card component should be a `div` element having `class=‘product’` and a data attribute called `data-item-id` containing the id of that product item. The card component should have the following: - An IMG element with src attribute containing the image URL and class name as `‘product__image’` - One `H3` element with class `‘product__name’` containing the product name - One P tag containing the product description with class `‘product__description’` - One H4 tag containing the price with class `‘product__price’` Use span tags for other product tags like memory, storage, colors (each). Given as a reference implementation. ## Data Source A global variable called `window.productList` ```javascript window.productList = [ { id: 1, name: 'Playstation 5', image: '....', description: 'Next gen Console gaming', price: '400', memory: '8 GB', storage: '1 TB', color: ['black', 'white', 'blue'], }, { id: 1, name: 'Playstation 4', image: '....', description: 'Previous gen Console gaming', price: '200', memory: '4 GB', storage: '1 TB', color: ['red', 'white', 'blue'], }, { id: 1, name: 'iPhone 12', image: '....', description: 'Smartphone', price: '650', memory: '4 GB', storage: '256 GB', color: ['black', 'white', 'blue', 'red'], }, .... ] ``` ## Expected Output Your submission should look like the following !E-commerce product search page(assets/expected_output.png)
