minus-squareKogasalink0•10 months agoIt’s probably valid javascript that returns “-1” or the empty string depending on if “b” is undefined or null
minus-square@murtaza64link3•edit-210 months agoYou don’t need the and right? Can’t it just be return a or b This doesn’t work if a is falsy non-null actually
minus-square@[email protected]linkfedilink1•10 months agoit’s just return a and b or c is the closest Lua has to a ternary operator, but yes, for the above you could shorten it to return a or b (“or returns the first argument if true, otherwise second argument is returned”)
→return a and a or b
return a or b
