You can’t use Ajax to connect to a third-party api because of CORS (Cross-Origin Resource Scripting). This means that building Snowmaha using only JavaScript is impossible unless some server-side code handles the request to the third-party api. Someone with above-average devops knowledge could setup a Lamda function and enable CORS for your site, but most people aren’t interested in learning how to use AWS Lamda, and why should they be? It has a horribly complex UX! Netlify Functions simplifies the process and sets up CORS for you. Now your site can make an Ajax request through Functions to Lamda and all of a sudden developers that only know HTML, CSS, and JavaScript are building “serverless” applications with the power of server-side functionality.
