what does argument do in filter function?

While I get filter function, I am unable to understand why there is a number parameter set in the function, like 

const events = numbers.filter((number) => number % 2 === 0);

while in normal function we do as following

function numbers(number){
   console.log(number % 2 === 0)
}
numbrers(2);

we pass an argument in the place of the argument, but in the filter I am unable to understand where we passed argument instead of number

The argument is just a shorthand syntax that represents each individual item that is being selected from the list of items by the filter.
