@s_jesse/lotide v1.0.0

Lotide

A mini clone of the Lodash library.

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

Install it:

npm install @s_jesse/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): checks to see if 2 array type values are equal and the assertion passes.
• assertEqual(actual, expected): assert function to compare primitive type values and see if it passes.
• assertObjectsEqual(obj1, obj2): assert function to compare two objects and see if it passes.
• countLetters(sentence): takes a sentence and returns the count of how many times each letter occurs in the sentence.
• countOnly(allItems, itemsToCount): takes a collection of items and is given what items we care about, will return a specfic subset of those items.
• eqArrays(arr1, arr2): takes two arrays and checks to see if they are equal and returns true or false accordingly.
• eqObjects(object1, object2): takes two objects and checks to see if they are equal and returns true or false accordingly.
• findKey(object, callback): searches for a key through the object using a callback function to return said key once it matches with a truthy value.
• findKeyByValue(obj, target): should find the key of an object when the value matches.
• flatten(arr): function will "flatten" nested arrays into single array.
• head(arr1): returns first element "head" of an array.
• letterPositions(sentence): takes a sentence and returns an index of where each character occurs in the sentence.
• map(array, callback): takes an array to map and returns new array based on results of callback function.
• middle(arr): should return the "middle" elements of an array, unless 2 or less values, then it should return empty array.
• tail(arrTail): should return an array without the first element.
• takeUntil(array, callback): takes an array and uses a callback function to return the array with desired outcome.
• without(source, itemsToRemove): should take in an array as a source and items to remove as second argument and then return the array without itemsToRemove.
