The functions portion of the JS course gives an example of a function:
const sumNumbers = number => number + number
Not trying to be super nitpicky, but wouldn’t this just return the single parameter number you feed it, added to itself? Wouldn’t a sumNumbers function need 2 parameters at least to be true to it’s name and actually sum numbers? Wouldn’t the function in the example be more aptly named twoN or something along those lines?
