Discussion on: Inline switch statements in javascript?

[Marek]

Try this:

(({ "key1": "val1", "key2": "val2"})[<key>] ?? "default value")

let val = (({ "4": "case1", "8": "case2"})["4"] ?? "Unknown")

val => "case1"

let val = (({ "4": "case1", "8": "case2"})["123"] ?? "Unknown")

val => "Unknown"
