Intersection Type

An Intersection Type takes two objects and creates a new object that combines the features of both objects.

Below is an example where we create an Intersection Type (ShapeProps) which combines all the properties defined for Square, Rectangle and Circle.

interface Square {
 kind: "square";

In the example below, we will:

update our local master branch to include the latest changes in GitHub's master branch
create a new branch to make code changes. We'll call this branch my-new-branch.
save code changes as commits on my-new-branch
share my-new-branch with GitHub (with the intent of opening a PR)
use git's rebase feature to reduce the number of commits to one commit (this is often referred to as squashing commits)

Example Workflow

It will also be necessary to add a key event handler that listens for the Space key in order to be consistent with native buttons.

Download actions can be implemented as links since downloads are considered destinations. Be sure to use the download attribute to "augment the inherent functionality of the link retrieving data. It side steps the attempt to render the file in the browser and instead says, “You know what? I’m just going to save this for later...". A link's inherit behavior lets users open in a new tab, copy the address or bookmark the link. More details about the download attribute: https://css-tricks.com/building-good-download-button/

From Eric Baily: I think a link styled like a button is fine, no aria ne
