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 @xavier-md/lotide

Require it:

const _ = require('@xavier-md/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

assertArraysEqual(actual, expected): Asserts whether two arrays contain strictly equal values at equivalent indices.

assertEqual(actual, expected): Asserts whether an actual value is strictly equal to an expected value.

assertObjectsEqual(actual, expected): Asserts whether the contents of two objects are strictly equal.

countLetters(letters): Returns an object that contains a counter for each character in a string.

countOnly(allItems, itemsToCount): Returns counts for a specific subset of items in an object.

eqArrays(array1, array2): Returns a boolean that indicates whether two arrays contain strictly equal values.

eqObjects(object1, object2): Returns a boolean that indicates whether two objects contain strictly equal values.

findKey(object, callback): Finds a key that adheres to a given callback value.

findKeyByValue(object, value): Finds a key by searching for its value.

head(array): Returns the first value of an array.

letterPositions(sentence): Returns the index of each letter from a given string in the form of an object, where each letter is a key and its value is the number of occurences.

map(array, callback): Iterates over every value of an array and returns a new array of changed values according to a given callback function.

middle(array): Returns the median of an array. Will return two values if the array's length is even.

tail(array): Returns everything in an array except for the first value.

takeUntil(array, callback): Pushes the values of a given array into a new array until a specified value is reached using a callback that functions as a condition. It then returns the new array.

without(source, itemsToRemove): Removes a specified item from a source array.
