Get optimized timeout for human reading speed using the text size

getToastTimeout.ts

// minimum timeout
const BASE_HIDE_TIMEOUT = 3000 //ms

export const getFlashTimeout = (message: string) => {
  const averageWordsPerSecond = 4 // average number of words per second a human can read
  const amountOfWords = message.split(" ").length
  const idealTimeout = (amountOfWords / averageWordsPerSecond) * 1000

  // factor in reading pauses for longer sentences
  const factor = Math.floor(amountOfWords / 10)
  const readingPause = 500 * 1.2 ** factor

  return Math.floor(Math.max(BASE_HIDE_TIMEOUT, idealTimeout + readingPause))
}
