Server-less functions are essentially server-side functions that are hosted on a third-party service. They are great as they essentially mean we can run them on someone else's server! All with the benefit of writing them in our own projects where the frontend code lives.

Netlify lets you deploy serverless Lambda functions without an AWS account, and with function management handled directly within Netlify. Your serverless functions are version-controlled, built, and deployed along with the rest of your Netlify site, and we will automatically handle service discovery through our built-in API gateway. This eliminates overhead and brings the power of Deploy Previews and rollbacks to your serverless functions.

We are going to build our first Netlify Serverless Function with 3 easy steps:

Step 1: Installing the Netlify command line interface
Step 2: File setup: so creating a directory to store your functions and writing a configuration file
Step 3: Learning the syntax

If you would like to use Netlify Functions in a real working example, please visit my Tik Tok Clone Video, in which we use them along with DataStax.
