map(i => i + 1)([1, 2, 3, 4, 5, [6, 7, 8, 9, 10]])
// => [2, 3, 4, 5, 6, "6,7,8,9,101" ]

let ap = require('apop/ap');
ap.recursive(ap.map(i => i + 1))([1, 2, 3, 4, 5, [6, 7, 8, 9, 10]])

Interactive Example:

let ap = require('apop/ap');
let formula = ap(
    ap.filter(currentValue => currentValue < 4), // => [3, 2, 1]
    ap.sort((a, b) => a - b), // => [1, 2, 3]
    ap.map(currentValue => ({id: currentValue})) // => [{id:1}, {id:2}, {id:3}]
);

formula([5, 4, 3, 2, 1])
// => [{id:1}, {id:2}, {id:3}]
