One of the first questions historically asked when developing a web-based application is Which desktop browsers and versions shall we support? These days, you should not be thinking so much about the software installed on the laptops and desktops of your users, but rather the devices they own.
The answer will still likely include a laptop or desktop, though no longer is it a safe assumption that these are the main devices your users use to interact with your application. Mobile phones, tablets, watches or skills for voice recognition devices such as Alexa could all be used, or depending on your target market, larger devices such as cars or even a vending machine! So, make sure that you think big and understand all the types of devices your customers and their customers might want to interact with your application.
