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?
The example in question is at the bottom of this screenshot:
