Introduction to AWS Step Function
What is AWS Step Function?
AWS Step Function is a “Function Orchestrator”. It’s a visual workflow service used to orchestrate AWS services, automate business processes, and build serverless applications.

Has it happened to you that a dependency which has been deprecated caused an error that took you almost a day (and entirety of your mental peace) to fix. I was the victim of this error most recently working on a React Native app.
React has recently made a lot of changes, most of them causing an error if you’re using an earlier version. I had this issue with navigation, where a lot of components have been moved.
