title: What is "lifecycle features" in React hooks?
body: <p>While learning hooks came across the definition</p>
  <blockquote>
  <p>Hooks are functions that let you “hook into” React state and lifecycle
  features from function components</p>
  </blockquote>
  <p><a href="https://reactjs.org/docs/hooks-overview.html" rel="nofollow noreferrer">https://reactjs.org/docs/hooks-overview.html</a></p>
  <p>but nowhere it's mentioned what is <code>lifecycle features</code> ?</p>
  <p>Couldn't find exact answer to this query googling as well</p>
