Description

I had run already implemented tests, but I think for react project it would be really nice to use jest with snapshot testing. One more idea would be to add eslint check as part of npm test command

The if/else block added in Block.jsx produces a lot of duplicate code. Perhaps there's a more elegant way to inject the time span.

{
  time
    ? <span className={ `${ns}-block-time` }>({ time })</span>
    : ''
}

Or you could just leave the time as N/A and test for it in the JSX and then it's a one line change to one file only.

<span className={ ${ns}-block-time}>{ time === "N/A" ? "" : "(" + time + ")" }</span>
