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 @baovevni/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): This function compares two arrays and only console logs an assertion pass or fail statement. There is no return value.
• assertEqual(actual, expected): This function compares two values and only console logs an assertion pass or fail statement. There is no return value.
• assertObjectsEqual(actual, expected): This function compares two objects and only console logs an assertion pass or fail statement. There is no return value.
• countLetters(sentence): This function takes the sentence and returns the count for each letter in the sentence skipping spaces.
• countOnly(allItems, itemsToCount): This function iterates through the array looking for the vlaues from itemsToCount and returns the count of each items from itemsToCount in the array.
• eqArrays(arr1, arr2): This function compares two arrays and returns a true if equal and false if arrays are unequal.
• eqObjects(object1, object2): This function compares two objects and returns a true if equal and false if arrays are unequal.
• findKey(object, callback): This function iterates through the object and returns a key from the callback function where the required key is specified.
• findKeyByValue(object, value): This function iterates through the object and returns a key by vlaue provided in the value argument.
• flatten(array): The function processes the input arrays element by element, flattening nested arrays and appending non-array elements directly to the result array.
• head(array): The function processes the input array returning first element of the array. It doesn't modify the input array.
• letterPositions(sentence): This function takes the sentence and returns the positions of every letter in the sentence.
• map(array, callback): This function transforms each element of an array using a callback function and returns a new array containing the transformed elements.
• middle(array): This function takes an array and returns a new array containing the middle value for odd-lengthed arrays and the two middle values for even-lengthed arrays.
• tail(array): This function returns a new array containing all elements of the input array except for the first element, preserving the original array if it is empty or has only one element.
• takeUntil(array, callback): This function iterates through an array until the callback function returns true for an element, returning a new array containing all elements before that point.
• without(source, itemsToRemove): This function removes specified items from a source array, returning a new array containing the remaining elements.
