One thing i don't entirely understand, why do we have to use cleaInterval and not clearTimeout? After all what You did was setTimeout not setInterval. Confusing

You have some of the best tutorials I’ve come across. Very concise topics with clear information, thank you.

@LNSFLIVE 2 месяца назад

how can you start the watcher again after stopping it?

@Vietnamkid1993 Год назад

Why are you using clearInterval instead of clearTimeout? @LearnVue

Hypothetically speaking, is it okay to use a watcher in a pinia store? Currently I have a schedules store that has a ref for start time and closing time as well as an array of schedules and an active schedule ref. Currently I'm watching the active schedule and if it changes updating the start and close times. I don't know why It just feels like I shouldn't be using a watcher in a store.

I wonder if you can break watchEffects with conditionals on a Math.random() > 0.5. Since in 1 branch it would never read `someRef.value` it wouldn't know that it should re-run when `someRef.value` changes. Yeah, a weird use case, I will agree.. Just thinking aloud..

Such a great video. However, do you know why onInvalidate is not define?

@jakubschulz4353 Год назад

Is it good practice to replace the standard watch with watchEffect?

How do i this typing.... Over server to another users screen?

@LearnVue 3 года назад

for that - you'd have to find a way to create constant communication with the server like firebase's realtime database, websockets, or something else.

@agastyasutra 3 года назад

@@LearnVue so if I use 🔥 firebase realtime database.... Then should I have to define a state.istyping in the server so that and update that variable data from watcheffect? So that I can update istyping to another users screen.
