Processing JSON using jq

jq is useful to slice, filter, map and transform structured json data.

Installing jq

On Mac OS

brew install jq

xta

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Async calls

When isLoading is true, the <div> is in the DOM, the <p> is not.
When isLoading is false, Vue will remove the <div> and add the <p> to the DOM,
at which point <MyComponent> will be created and passed the fetched data.
