const _ = require('@meteora277/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

assertArraysEqual(arr, arr): Accepts 2 arrays and asserts if they are equal or not.

assertEqual(value, value): Accepts 2 primitive values and asserts if they are equal.

assertObjectEqual({obj},{obj}): Accepts 2 objects and asserts if they are equal.

countLetters(string): Accepts a string and returns an object counting how many times a character appears inside the string.

countOnly([arr], {obj}): Accepts an array and an object, countOnly() will only count items in the array that are true within the onject.

eqArrays(arr, arr) Accepts 2 arrays and compares all items to be equal. Returns true or false.

eqObjects({obj}, {obj}) Accepts 2 objects and compared all keys and values. Returns true or false.

findKey({object}, callback): Accepts an Object and a callback, returns the key of the first value of the object passed through the callback that returns true.

findKeyByValue({obj}, value) : Accepts an Object and a value. findKey() will then return the first key that is equal to the value.

flatten([arr]) Accepts an array, if there is nested arrays, it will remove the nesting.

head(arr) Accepts and array, will return index0 or the the "head" of the array.

letterPositions(): Accepts a string and returns an object. object keys are the characters in the string, and it's values are the index of where it appears in the string.

map(arr, callback): Accepts an array and a callback, calls the callback on al lthe values of the array and returns a new array.

middle(arr): Accepts an array and return 2 middle items if arr.length is even, if odd just the single most middle item.

tail(arr): Accepts an array and returns everything besides index0.

takeUntil(arr, callback): Accepts an array and returns items until callback is fulfilled.

without(arr, arr) Accepts 2 arrays, will remove from the first array, items that appear in the second.
