- “In Vue 3 we have watch and watchEffect in the composition API.” — @fimion [0:02:02]
- “With the composition API, you can now import from Vue watch or watchEffect. WatchEffect allows you to define a function that accesses some reactive value.” — @fimion [0:03:43]
- “So when we're passing complex objects to the watch function, it doesn't immediately want to be able to show you the old version and the new version. We kind of got to do some stuff to it.” — @fimion [0:08:45]
- “Sometimes watch is not the correct answer. It's a very powerful tool. It can do a lot of really good and cool things. May not always be the correct answer, however.” — @fimion [0:23:04]
