> array = [
{fname: 'John', lname: 'Woo', lng: 1, lat: 2},
{fname: 'John', lname: 'Foo', lng: 7, lat: 8}
];
> format = applyFnMap({
coords: _.collect([_.getKey('lng'), _.getKey('lat')]),
fullname: _.pipe([
_.collect([_.getKey('fname'), _.getKey('lname')]),
_.joinWith(' ')
]),
});
> formatted = _.map(raw, format)
[
{coords: [1, 2], fullname: 'John Woo'},
{coords: [7, 8], fullname: 'John Foo'}
]
> checkNumber = applyFnMap({
range: _.collect([_.add(1), _.deduct(1)]),
sign: Math.sign,
})

{range: [2, 0], sign: 1}
> checkNumber(-10)
{range: [-9, -11], sign: -1}
> checkString = applyFnMap({
parts: _.splitBy('/'),
