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 @lmtpox/lotide

Require it:

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

Call it:

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

Documentation

For examples of all implemented functions:

npm run test

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Compares two arrays, gives assertion if equal.
• assertEqual(actual, expected): Compares two values, gives an assertion if equal.
• assertObjectsEqual(actual, expected): Compares two objects, gives an assertion if equal.
• countLetters(string): Counts the amount of letters in a given string.
• countOnly(allItems, itemsToCount): Takes an array of strings, and an object specifying what to count. Returns the number of occurences.
• eqArrays(arr1, arr2): Takes in two arrays and returns a boolean depending on if they are equal.
• eqObjects(object1, object2): Takes in two objects and returns a boolean depending on if they are equal.
• findKey(obj, callback): Takes in an object and a callback that checks for something within said object, and returns the key if found.
• findKeyByValue(obj, content): Takes in an object and the content of a key, then returns the key that contains said content.
• flatten(array): Takes in an array containing an array and flattens them to a single-level array.
• head(array): Takes in an array and returns the first element in it.
• letterPositions(string): Takes in a string and returns an object that lists the letters and their positions.
• map(array, callback): Takes in an array and a callback then returns an array based on the callback's specification.
• middle(array): Takes in an array and returns the middle element(s).
• tail(array): Takes in an array and returns the last element in it.
• takeUntil(array, callback): Takes in an array and callback that specifies a point to cut off. Returns an array that includes elements up until the element specified by the callback.
• without(array, toRemove): Takes in array and an array of elements to be removed from the first array. Returns a new array with the remaining values.
