@chatcher20/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 @chatcher20/lotide

Require it:

const _ = require('@chatcher20/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(a, b): compares two flat arrays
• assertEqual(a, b): compares two primitive values
• assertObjectsEqual(a, b)): compares two flat objects
• countLetters(a): returns an object with each unique letter as keys and how many instances each value occurs.
• countOnly(a, b)): looks at an array (a) and returns an object with each unique item as keys, ad nd occurencs of each value. B filters the objects
• eqArrays(a, b)): compares two arrays, and returns true if a and b are identical
• eqObjects(a, b)): compares two objects, and returns true if a and b are identical
• findKey(a, fn): searches object (a) for the first key which satisifies a given callback function (fn) and returns that key.
• findKeyByValue(a, b)): searches the values (b) of object (a) and returns its key
• flatten(a): returns an array that is flattened by one level
• head(a): this will return the first item ("head") in an array
• letterPositions(a): returns an object containing all unique elements (letters) of a string as keys, and outputs the position of those elements as the values for the key:value pairs
• map(a, fn): returns a new array with the elements of an input array (a) which have been manpualed by callback function (fn)
• middle(a): returns the middle value (or two middle values) of a given array. Arrays with an even number of elements will return two middle values.
• tail(a): this will return everything BUT the first item in an array (opposite of head)
• takeUntil(a, fn): dreturns items from the start of an array until the callback function condition is met.
• without(a, b)): returns an array that has all of the elements from array a but with the elments from array b removed.
