How to append an array of objects to a card element in javascript

Question

I am very new to javascript and I am working on a small project. I have a small array of objects in my javascript file that I want to create and populate product cards with.

my current set up of the product card is about 20 lines, I have taken the approach to see if I could use document.createElement... append element, etc and after doing so I ran into some problems with my objects seemingly being undefined plus I need to be able to append into the tags so thay i can define classes and id's so that my css will pick up on the code and make it pretty eg <div class = "test>" . Overall it's just a mess and will take triple the lines of code required to build the card.

here is a snippet of my javascript array

       window.products = [
    {
        name: "Berry Leash",
        img: 'src="images/leashes/berry.jpg" alt="berry leash"',
        price: 14.99,
        onsale: 0.0,
        tags: "Leash",
        description: "A fresh taste on a collar,"
    },

and here is a snippet of the card layout i am going to be using.

 <div class="product-card">
            <div class="badge">Hot</div>
            <div class="product-tumb">
                <img src="images/dog-running.jpg" alt="" />
            </div>
            <div class="product-details">
                <span class="product-catagory">dog1,dog2</span>
                <h4><a href="">big boy</a></h4>
                <p>
                    Lorem ipsum dolor sit amet, consectetur adipisicing elit.
                    Vero, possimus nostrum!
                </p>
                <div class="product-bottom-details">
                    <div class="product-price">
                        <small>$96.00</small>$230.99
                    </div>
                    <button>buy now</button>
                    <div class="product-links">
                        <a><i class="fa fa-heart"></i></a>
                        <a><i class="fa fa-shopping-cart"></i></a>
                    </div>
                </div>
            </div>
        </div>

I am hoping to populate the page with as many cards as there are objects in the array.

My results so far have just been undefined and basically a mess of code, I can provide the code I'm using but it is useless and I don't want to build on it. I have heard of .map being useful but im not sure use it to its full potential.

You can use JS to loop over each product, combine the product using the template literal syntax ( ${variable} ), and then reinject it into the DOM.

Example:

 products = [ { name: "Berry Leash", img: 'src="images/leashes/berry.jpg" alt="berry leash"', price: 14.99, onsale: 0.0, tags: "Leash", description: "A fresh taste on a collar," }, { name: "Tommy Leash", img: 'src="images/leashes/berry.jpg" alt="berry leash"', price: 14.99, onsale: 0.0, tags: "Leash", description: "A fresh taste on a collar," } ] products.forEach(product => { var div = document.querySelector('div') div.innerHTML = div.innerHTML + ` <div class="product-card"> <div class="badge">Hot</div> <div class="product-tumb"> <img src="images/dog-running.jpg" alt="" /> </div> <div class="product-details"> <span class="product-catagory">dog1,dog2</span> <h4><a href="">${product.name}</a></h4> <p> ${product.description} </p> <div class="product-bottom-details"> <div class="product-price"> <small>$96.00</small>${product.price} </div> <button>buy now</button> <div class="product-links"> <a><i class="fa fa-heart"></i></a> <a><i class="fa fa-shopping-cart"></i></a> </div> </div> </div> </div> <br /> <br /> ` }) 

 <div></div>
