I started a demo example showing how to leverage <a href="https://fosstodon.org/tags/FastCheck" class="mention hashtag" rel="tag">#<span>FastCheck</span></a> against exercises coming from Cracking the Coding Interview in <a href="https://fosstodon.org/tags/JavaScript" class="mention hashtag" rel="tag">#<span>JavaScript</span></a> at <a href="https://github.com/dubzzz/cracking-pbt" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="">github.com/dubzzz/cracking-pbt</span><span class="invisible"></span></a></p><p>More demos to come (race conditions..)</p>
