Arrow function is skipped

I don't see anything wrong with this arrow function but even if I replace position with the number 2, it still doesn't run its internals

const isValidMove = (position) => {
console.log("a")
const valid = !isNaN(+position);
return valid;
}


I don't get anything logged to the console even with this:

const isValidMove = (2) => {
console.log("a")
const valid = !isNaN(+position);
return valid;
}


How are you calling the function? And version 2 is a syntax error.

Also, which console are you looking at? When I "run" version 2, I get SyntaxError: missing formal parameter

You've made a fine arrow function, but you're not calling it properly. isValidMove will be a function based on your first snippet. To use it, you just need to call it and pass the position argument with isValidMove(2). Try this instead:

isValidMove

position

isValidMove(2)

const isValidMove = (position) => {
console.log("a")
const valid = !isNaN(+position);
return valid;
}

console.log(isValidMove(2))

omg didn't even see that thx
