"If I want to be taken seriously?" Was that bit of petty oneupmanship really necessary? I assure you, Alex, I'm completely unconcerned with whether you take me seriously. You were probably just trying to show off. But in case you weren't, here's how JS works. In JavaScript, if you're passing in a function as a parameter, the normal way is to use an arrow function. Like this: `array.map((element) => yourFunction(element));`. This gives you explicit control over which parameters are passed in to your function and how. As a shortcut, you can provide a function name rather than an arrow function. If you do so, you're saying that you want all parameters to be passed to that function. You're expected to know what those parameters are and how the function you're passing in will use them. If you don't know that, well, you're programming blind and bad things will sometimes happen. Maybe don't do that. As with many things in JavaScript, it's better to be explicit than rely on the shortcut. Edit: Just to be clear, here's the correct way to map an array of strings to an array of numbers in JavaScript: `array.map((s) => parseInt(s, 10));`
