import React, { useEffect } from 'react';
import { useRouter } from 'state';

// Component that attaches scroll to top hanler on router change
// renders nothing, just attaches side effects
export const ScrollToTopControlller = () => {
  // this assumes that current router state is accessed via hook
  // but it does not matter, pathname and search (or that ever) may come from props, context, etc.
  const  { pathname, search } = useRouter();

HoC (pattern) vs Render Props (pattern) vs Hooks (not pattern, a new API)

Someone was asking me about comparing the HoC and Render Props patterns (and their shortcomings) to hooks. I might leave this up as a public gist for others if it's helpful.

tldr;

Issues with HoC:

let autoNext = () => {
  Array.from(document.querySelectorAll('button'))
    .filter(b => b.textContent === 'Continue to next module')
    .forEach(b => b.click());
};

setInterval(autoNext, 2500);
