How to use the global-cache.delete function in global-cache

t('useGlobalCache: must be writable', async t => {
  globalCache.set('x', 1)

  let log = []

  enhook(() => {
    let [x, setX] = useGlobalCache('x')
    log.push(x)
    setX(2)
  })()

  t.deepEqual(log, [1])
  await tick(3)
  t.deepEqual(log, [1, 2])

  globalCache.delete('x')
  t.end()
})

t('useGlobalCache: does not trigger unchanged updates', async t => {
  let log = []
  let f = enhook((i) => {
    let [count, setCount] = useGlobalCache('count', i)
    log.push(count)
    useEffect(() => {
      setCount(i + 1)
      setCount(i)
    }, [])
  })
  f(1)
  t.deepEqual(log, [1])
  await frame(3)
  t.deepEqual(log, [1])

  globalCache.delete('count')
  t.end()
})
