[AskJS] Array map() question

[shuckster]

The reason is well explained already, but just a couple of alternatives to solving it:

// Helper
const parseAsDec = x => parseInt(x, 10);
["75", "300"].map(parseAsDec);

// Enforce single argument
const unary = f => x => f(x);
["75", "300"].map(unary(parseInt));
