Synchronous time slicing

[yisar]

This is a time slicing implement way suitable for Vue, which can effectively alleviate Jank.

It's very intrusive, the same as the current behavior, and it's coarse-grained and doesn't sacrifice the time of the microtask.

Thank you~

I don't think your understanding of rAF is correct.

Promise.resolve().then(() => {
  console.log('micro')
  requestAnimationFrame(() => {
    console.log('raf')
  })
  setTimeout(() => {
    console.log('timeout')
  }, 0)
}).then(() => {
  console.log('chained micro')
})

The output will be

• micro
• chained micro
• timeout
• raf

There's just no way rAF can be used for "synchronous" time slicing.

Closing since I don't think this is actually feasible unless a prototype can prove otherwise.
