Can anyone elaborate on what this is? I've read the article, but have no idea what gact is.

They are proposing a change the way the lifecycle of a React component is computed. Right now:

    if (someCondition) {
      return <div><Thing /></div>
    } else {
      return <Thing />
    }

will result in `Thing` going through the unmount / re-mount portion of the component lifecycle every time `someCondition` changes. This proposal suggests that instead `Thing` should remain mounted. It has been suggested (in the linked issue https://github.com/facebook/react/issues/16316) that there is a plan to make this possible at some point via something termed "re-parenting".

Looks like they're trying to make a point about an issue they posted.. https://github.com/facebook/react/issues/16316

Gact is a new framework that will be released in the coming months.

In the time leading up to its release, I am releasing a series of documents explaining core ideas.
