Install it:

npm install @samgiorgievski/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns first item in array
• tail(array): returns array that includes everything after the first item in the array
• middle(array): returns the middle item in array, if even, returns 2 of the middle items
• assertArraysEqual(array1, array2): compares arrays to check if they are equal
• assertEqual(actual, expected): compares two values to check if they are equal
• eqArrays(array1, array2): Returns true if arrays are equal, otherwise false
• countOnly(allItems, itemsToCount): take in a collection of items and return counts for a specific subset of those items
• countLetters(string): Input string and return object where key = character, and value = how many are in the string
• findKey(object, callback): scan the object and return the first key for which the callback returns a truthy value
• findKeyByValue(object, value): search for a key on an object where its value matches a given value
• letterPositions(string): return all the indices (zero-based positions) in the string where each character is found
• map(array, callback): creates a new array populated with the results of calling a provided function on every element in the calling array
• takeUntil(array, callback): returns a slice of array up until callback value is true
• without(array, itemsToRemove): takes in array, removes itemsToRemove, and returns new array
• eqObjects(object1, object2): return true if both objects are equal
