in strict mode IIRC, the useEffect runs two times

#

so the data is populated first time

#

but then again data is getting added to the array

#

would you explain what you're trying to do? to explain the answer better

i am trying to get all different eventUpdates from the function getEventUpdates

#

so if there are duplicates they wouldnt be added to the array

neon yacht
#

so you get like new update of that event everytime the eventId is changed?

finite trail
#

no i just get a few same objects everytime it is called, but somewhy the function gets called two times, so there are duplicates

neon yacht
#

you can disable strict mode if you want?

^ to disable in next.js

#

^ in good old react

finite trail
#

removing duplicates is more reliable, because changing strict mode could couse my other functions to break

neon yacht
#

noice

#

I saw somewhere, that strict mode should not cause issues for our code

#

IDK

#

ill try to fix by removing duplicates, this code almost seems right, just a small mistake somewhere here

neon yacht
#

yeah, good luck

#

Use a Set instead of an Array. It's a data type which does not allow duplicates

finite trail
#

i need to keep the order of the items

mint dock
#

Sets are ordered

finite trail

i get an error trying to map the set, can you map them??
