I love building web apps with JavaScript and I almost always need an API to serve my data or connect to a behind-the-scenes service. Azure Functions makes this wicked easy. In fact, it takes a just a few minutes.
Brian Clark and I share my screen in the video below as we create an Azure Function end-point together. Then we hit it from postman using its public url. Feel free to follow along by trying Azure Functions at this link.
You can sign up for the free trial on Azure yet from this link.
