[Pavlo Liapota]

You can write map.getValue(key)

[Bernhard]

perfect, thank you!

[Czar]

I'd do this: (1..10).asSequence().mapNotNull { map[it] }

[Czar]

where (1..10).asSequence() is an example sequence of prospective keys, as I don't know what's your sequence like, and map is your map.

[Bernhard]

yeah I’m mapping over a different list and join elements from a map into it

[Bernhard]

kinda like a zip() function but with a more complex way to combine them than an index

[Czar]

basically, use mapNotNull(map::get) instead of filter(map::containsKey).

[Czar]

Pavlo's suggestion will throw if the map doesn't have an entry with the specified key, unless the map has default provider
