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 @amusictheorist/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(...): returns the head of an array (index [0])
• tail(...): returns the tail of an array (everything except index [0])
• middle(...): returns the middle of an array; if array has an even length, it returns the two middle indices, if it has an odd length, it returns the middle index
• assertEqual(...): an assertion function to write tests
• eqArrays(...): a function that checks whether the contents of two arrays are identical or not
• assertArraysEqual(...): an assertion function to test whether the content of two arrays is identical or not
• eqObjects(...): a function that checks whether the contents of two objects are identical or not
• assertObjectsEqual(...): an assertion function to test whether the content of two objects is identical or not
• countLetters(...): lists each letter in a string and how many times it occurs in the string, ignoring spaces
• countOnly(...): counts how many times a given element appears in an array
• findKey(...): finds the key in an object that matches the specified input
• findKeyByValue(...): finds the key in an object that matches a specified value
• letterPositions(...): returns an array listing the indices in which a specified letter within a string is found
• takeUntil(...): returns the elements of a given array until it finds a falsey value
• without(...): compares the elements of two arrays and returns the elements not found in both arrays
• flatten(...): takes an array with nested arrays (only one level down) and returns the same elements in the same order without nested arrays
