npm install @katieherda/lotide

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): compares two arrays and prints whether they match or not.
• assertEqual(actual, expected): compares two values and prints whether they match or not.
• assertObjectsEqual(actual, expected): compares two objects and returns true or false, based on a perfect match.
• countLetters(inputString): takes in a string and returns a count of each letter in that sting.
• countOnly(allItems, itemsToCount): takes in a collection of items and return counts for a specific subset of those items.
• eqArrays(arrayOne, arrayTwo): takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(object1, object2): take in two objects and returns true or false, based on a perfect match.
• findByKeyValue(objects, value): takes in an object and value. Return the first key which contains the given value.
• findKey(object, callBack): takes in an object and callback. It scans object and return the first key which the callback returns a truthy value for.
• head(array): returns the first element from the array.
• letterPositions(string): takes in a string and returns all the indices in the string where each character is found
• map(array, callBack): returns a new array based on the results of the callback function.
• middle(array): take in an array and return the middle-most element(s) of the given array.
• tail(array): returns all items in an array except for the first item.
• takeUntil(array, callBack): returns a slice of an array with elements taken from the beginning and elements following until the callback/predicate returns a truthy value.
• without(array, itemsToRemove): returns a subset of a given array, removing unwanted elements.
