Method list

chunk

Create an list of elements split into groups the length of initial list size.

Tooly.chunk([1, 2, 3, 4, 5], 2);
// [[1, 2], [3, 4], 5]

compact

Create a list without null, false, 0 and '' from another list.

Tooly.compact([0, 77, '', 55, false]);
// [77, 55]

concat

Create a list that contain the initial list and additional list.

Tooly.concat([1, 2, 3], [4, 5, 6]);
// [1, 2, 3, 4, 5, 6]

difference

Create a list of values that not include in the second list.

Tooly.difference([1, 2, 3], [3, 4, 5]);
// [1, 2]

drop

Create a list with n elements dropped from the beginning.

Tooly.drop([1, 2, 3], 2);
// [3]

fill

Fills elements of list with value from start up to, but not including end.

Tooly.fill([1, 2, 3, 4, 5], '*', 1, 3);
// [1, *, *, 4, 5]

findIndex

Find value index of list.

Tooly.findIndex([1, 2, 3], (e) => e == 2);
// 1

findLastIndex

Find value index of list but it iterate over elements of list from right to left.

Tooly.findLastIndex([1, 2, 3], (e) => e == 2);
// 1

flatten

Flattens list a single level deep.

Tooly.flatten([1, 2, [3, 4], ['a', 'b']]);
// [1, 2, 3, 4, a, b]

indexOf

Gets the first index of value in the list.

Tooly.indexOf([1, 2, 3, 4], 4);
// 3

listToString

Create a string from a list.

Tooly.listToString(['first', 'second', 'third']);
// first, second, third

uniq

Create a list no duplicate elements from another list.

Tooly.uniq([1, 1, 1, 5, 5, 8]);
// [1, 5, 8]

dropRight

Create a list with n elements dropped from the end.

Tooly.dropRight([1, 2, 3, 4], 1);
// [1, 2, 3]

first

Gets the first element of list.

Tooly.first([1, 2, 3]);
// 1

flattenDeep

Flattens list recursively.

Tooly.flattenDeep([1, [2, [3, [4]], 5]]);
// [1, 2, 3, 4, 5]

initial

Gets all but the last element of list.

Tooly.initial([1, 2, 3]);
// [1, 2]

join

Converts all elements in list into a string separated by separator.

Tooly.join(['a', 'b', 'c'], '~');
// a~b~c

last

Gets the last element of list.

Tooly.last([1, 2, 3]);
// 3

nth

Gets the element at index n of list. If n is negative, the nth element from the end is returned.

Tooly.nth([1, 2, 3, 4], 1);
// 2

Tooly.nth([1, 2, 3, 4], -2);
// 3

sum

Calculates the sum of a list of numbers.

Tooly.sum([1, 2, 3, 4]);
// 10

take

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

Tooly.take([1, 2, 3, 4], 2);
// [1, 2]

takeRight

Creates a slice of list with n elements taken from the end.

Tooly.takeRight([1, 2, 3, 4], 2);
// [3, 4]
