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 @tapansiwach/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): Uses eqArrays function in this library to check for equality and then asserts if the two arrays are equal.
• assertEqual(actual, expected): Asserts if two input values (of primitive types) are equal.
• assertObjectsEqual(object1, object2): Uses eqObjects function in this library to check for equality and then asserts if the two objects are equal.
• countLetters(sentence): Counts the frequency of occurance of different letters in a sentence
• countOnly(array, object): Counts the frequency of occurance of items in an array if they are described as to be counted via a given object.
• eqArrays(array1, array2): Checks if two arrays are equal.
• eqObjects(object1, object2): Checks if two objects are equal.
• findKey(object, callback): Finds a key in an object which satisfies the condition evaluated through a given callback.
• findKeyByValue(object, value): Finds an object's key corrosponding to a provided value.
• flatten(deepArray): Flattens a deep / nested array.
• head(array): Returns the first item of an array.
• letterPositions(sentence): Returns an object which contains the position(s) of diferrent letters in a sentence.
• map(array, callback): Maps the items of an array as per a provided callback.
• middle(array): Returns the middle (if length of an input array is odd) or middle two items (if length of an input array is even) of an array.
• tail(array): Returns the last two indicesc of an array.
• takeUntil(array, callback): Returns an array containing items of a provided array until an item in the provided array meets a condition (defined by a callback).
• without(array1, array2): Returns an array which contains items in a source array (array1) without the items contained in another array (array2).
