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 @username/lotide

Require it:

const _ = require('@rohan-batra/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1,arr2): Takes in two arrays and console.logs an appropriate message to the console.
• assertEqual(Str1,Str2): Compare the two values it takes in and prints out a message telling us if they match or not.
• assertObjectsEqual(Obj1,Obj2): Takes in two objects and console.logs an appropriate message to the console.
• countLetters(String): Takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly([array]): Takes in a collection of items and return counts for a specific subset of those items
• eqArrays([array1],[array2]): Compares two arrays and returns true or false, based on a perfect match
• eqObjects(Obj1,Obj2): Takes in two objects and returns true or false, based on a perfect match.
• findKey(Object, callback): Takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue(Object, value): Takes in an object and a value. It scans the object and returns the first key which contains the given value. If no key with that given value is found, then it returns undefined.
• flatten(array): Takes in an array of arrays and returns a "flattened" version of the array
• head(array): Retrieves the first element from an array
• letterPositions(string): Returns all the indices (zero-based positions) in the string where each character is found.
• map(array,callback): Creates a new array as a result of a callback function implemented on each element of teh array.
• middle(array): Returns the middle-most element(s) of the given array.
• tail(array): Retrieves every element except the head (first element) of the array
• takeUntil(array,callback): Returns a "slice of the array with elements taken from the beginning." It will keep going until the callback/predicate returns a truthy value.
• without(source array, itemsToRemove array): Return a subset of a given array, removing unwanted elements.
