var filterArray = require('@f/filter-array')
filterArray(isEven, [1,2,3,4,5]) // -> [2, 4]
function isEven (n) {
return n % 2 === 0
}fn- The predicate function that decides whether the value is kept. Receives(value, index)for each value in the array.arr- The array to filter
Returns: A new array containing only the values for which fn(value, index) returned truthy.
