@consensusai/lotide v1.0.1

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 @consensusai/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): Compares two values with === and logs result of comparison.
• eqArrays(array1, array2): Compares two arrays to assess equality.
• assertArraysEqual(actualArray, expectedArray): Logs result of eqArrays.
• eqObjects(object1, object2): Compares two objects to assess equality.
• assertObjectsEqual(originalArray, comparedArray): Logs result of eqObjects.
• countLetters(string): Counts how many times a letter appears in a string.
• countOnly(allItems, itemsToCount): Returns an object containing values in an array, matching a passed array of items to count, as keys with the amount of times they appear as the key value.
• findKey(object, callback): Returns the key of a passed object when the value of the key passed into a callback function evaluates to true.
• findKeyByValue(object, value): Returns the key of a passed object that matches a passed value.
• flatten(array): Returns an array that joins nested array values with the outermost array.
• head(array): Returns the value at index 0 of an array passed as an argument.
• letterPositions(string): Returns an object with letters of a string passed as an argument as keys with the indices they appear at as values.
• map(array, callback): Returns an array containing the return values from a callback acting on each value of a passed array.
• middle(array): Returns the middle value(s) of a passed array. Returns undefined if the passed array has a length of 2 or less.
• tail(array): Returns an array containing all the indices after 0 of a passed array.
• takeUntil(array, callback): Returns all the values of a passed array until a passed callback evaluates to true.
• without(source, itemsToRemove): Returns an array with items to remove filtered out.
