Available Functions

chunk

Divides the array into blocks of given number and return it.

let result =Funcpack.chunk(['a', 'b', 'c', 'd'], 2)
//=> [["a", "b"], ["c","d"]]

compact

Creates an array with all falsy values removed. The values false, null, 0, "", undefined, and NaN are falsy.

let result=Funcpack.compact([0, 1, false, 2, '', 3]);
// => [1, 2, 3]

defer

Defers invoking the func until the current call stack has cleared. Any additional arguments are provided to func when it's invoked.

Funcpack.defer(function(text) {
  console.log(text);
}, 'deferred');
// => Logs 'deferred' after one millisecond.

drop

Creates a slice of array with n elements dropped from the beginning.

Funcpack.drop([1, 2, 3]);
// => [2, 3]
Funcpack.drop([1, 2, 3], 0);
// => [1, 2, 3]

####fill Fills elements of array with value from start up to, but not including, end.

var array = [1, 2, 3];
 Funcpack.fill(array, 'a');
console.log(array);
// => ['a', 'a', 'a']

head

Gets the first element of array.

Funcpack.head([1, 2, 3]);
// => 1

rest

Funcpack.rest('hello', 'fred', 'barney', 'pebbles');
// => 'hello fred, barney, & pebbles'

some

Checks if predicate returns truthy for any element of collection. Iteration is stopped once predicate returns truthy. The predicate is invoked with three arguments: (value, index|key, collection).

Funcpack.some([null, 0, 'yes', false], Boolean);
// => true

tail

Gets all but the first element of array.

Funcpack.tail([1, 2, 3]);
// => [2, 3]

take

Creates a slice of array with n elements taken from the beginning.

Funcpack.take([1, 2, 3]);
// => [1]

Funcpack.take([1, 2, 3], 2);
// => [1, 2]

zip

Creates an array of grouped elements, the first of which contains the first elements of the given arrays, the second of which contains the second elements of the given arrays, and so on.

Funcpack.zip(['a', 'b'], [1, 2], [true, false]);
// => [['a', 1, true], ['b', 2, false]]
