In sum, Joseph argues for a four-point approach to achieving maximum performance in your web-app:
  • Be lazy: Don’t load or do things before you need to; maybe you won’t need to load or do them at all.
  • Be responsive: Make things happen quickly. If you can shave 100ms off of an interaction by responding to a mousedown event instead of a click event, do it.
  • Be pragmatic: Frontend engineering is hard enough. Don’t make it harder than it needs to be.
  • Be vigilant: Blank web pages are fast. Web pages become slow because you put stuff in them; slowness is your resonsibility. Vigilance is required to prevent slowness.
