In this course you will build three actions that each accomplish different tasks designed to demonstrate the flexibility of creating and consuming JavaScript Based Actions.
First, you will start with the traditional "Hello World!" program which will teach you where to find the output of a workflow run. You will then modify this "Hello World!" action to accept input parameters which allow the action to be more dynamic.
Second, you will write an action that call upon an external API to retrieve a fact about cats and prints it to the workflows output. You will then modify this cat fact action to set the retrieved data as output for another action in the workflow to consume.
Lastly, you will write a third action that will open an issue in your repository making the cat fact available to everyone. You will learn how to use the output of previous actions as input for current actions in this step.
