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 i @lstaff4/lotide

Require it:

const _ = require('@lstaff4/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): A version of assertEqual made for arrays. Always expects the result to be true, and the Assertion will fail if they are not.
• assertEqual(actual, expected): Compares what you expect a function to produce and the actual process and console logs whether or no they are equal. Does not work with arrays.
• assertObjectsEqual(actual, expected): A version of assertEqual made for objects. Always expects the result to be true, and the Assertion will fail if they are not.
• countLetters(string): Counts the number of times all letters appear within a string and returns an object with the complete list.
• countOnly(allItems, itemsToCount): Counts the number of times an item appears within an array. Returns an array with all designated items counted.
• eqArrays(arr1, arr2): Compares two arrays and determines if they are equal.
• eqObjectst(object1, object2): Compares two objects and determines if they are equal.
• findKey(object, callback): Returns the first key that fits within the callback's parameters.
• findKeyByValue(keyList, value): Returns a key by searching through the keyList for its value.
• flatten(nestedArray): Creates an array with all nested values of a prior array un-nested.
• head(array): Returns the first item in an array.
• letterPositions(sentence): Returns an array with the positions of each letter in a given string.
• map(array, callback): A function that uses callbacks to return a new array with custom parameters based on the callback.
• middle(array): Returns the middle item(s) of an array. Returns one item if the array is odd, and two if it is even.
• tail(array): Returns an array without its first item.
• takeUntil(array, callback): Pushes objects from an array into a new array until the callback's parameters are met. Returns the new array.
• without(source, itemsToRemove): Creates an array without selected items from a prior array.
