Also being limited such that you need to nest the extremely deeply if you, for whatever, you need to have a complex inline condition. I like the case expression , although I mostly know it from erlang. permalink fedilink source parent [–] Sv443@sh.itjust.works 6 points 11 months ago* (1 child) I've been called slurs before for using immediately invoked anonymous function expressions with switch cases in JS const [val1, val2] = (() => { switch(whatever) { case "foo": return [1, 2]; case "bar": return [3, 4]; default: return [0, 0]; } }))(); permalink fedilink source parent hideshow 2 child comments replies: [–] gandalf_der_12te@lemmy.blahaj.zone 3 points 11 months ago (1 child) const [val1, val2] = ({ "foo": [1, 2], "bar": [3, 4], })[whatever] || [0, 0]; permalink fedilink source parent hideshow 2 child comments replies: [–] Sv443@sh.itjust.works 2 points 11 months ago 🤫 permalink fedilink source parent
