Purpose
BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.
This project was created and published by me as part of my learnings at Lighthouse Labs.
Usage

npm install @metaphive/lotide
Require it:
const _ = require('@metaphive/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
head(arr)
: Retrieves the first element of an array. -
tail(arr)
: Retrieves all other elements except the head. -
middle(array)
: Takes in an array and returns the middle-most elements. -
flatten(array)
: Takes in an array of arrays and returns a single array. -
findKeyByValue(obj,objVal)
: Takes in an object and a value. It should scan the object and return the first key which contains the given value. -
findKey(ObjectToTraverse,Callback)
: Takes in an object and a callback. It will traverse the object and return the first key for which the callback returns a truthy value. If no key is found, then it will return undefined. -
eqArray(array1,array2)
: Takes in two arrays and returns a true or false value. -
countOnly(allItems,ItemsToCount)
: Takes in an array of strings and returns an object with the appropriate counts. -
countletters(phrase)
: Takes in an array of strings and returns an object with the unique letter count. -
letterPositions(phrase)
: returns all the indicies in the string where each character is found. -
assertObjectEqual(array)
: Takes in two objects and console.log(s) an appropriate message based on the result. -
assertEqual(array)
: Takes in two values and prints a message to the console indicating if there was a match or not. -
assertArraysEqual(actual,expected)
: Takes in two arrays and logs the appropriate message. -
without(source,itemsToRemove)
: Takes in an array and itemsToRemove returning a subset of a given array, removing unwanted elements. -
takeUntil(newArr,callback)
: Takes in an Array and a Callback, returns a slice of the array taken from the beginning until the callback function returns a truthy value. -
map(array,callback)
: Takes in an array and a callback and returns a new array based on the results of the callback function. -
eqObjects(Object1,Object2)
: Takes in two objects and returns true or false, based on a perfect match.
