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 @mbbaltaji as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @mbbaltaji/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Function that asserts if two arrays are equal.
• assertEqual(prim1, prim2): Function that asserts if two primitives are equal.
• assertObjectsEqual(obj1, obj2): Function that asserts if two objects are equal.
• countLetters(string): Function that returns letter count of a given string.
• countOnly(items, itemsToCount): function that takes items and returns count of speciefied items.
• eqArrays(arr1, arr2): Functions that compares two arrays and returns true if they're equal.
• eqObjects(obj1, obj2): Function that takes two objects and returns true if the objects are an exact match.
• findKey(obj, callback): Function that takes in object and a callback, returns the key if the call back function is satisfied.
• findKeyByValue(obj, val):function that taken in an object and a value. Returns the key of the given value.
• flatten(NestedArray): Function that takes in a nested array and returns a flattened/unnested array containing all values of the nested array.
• head(array): Function that takes in an array and returns the head(first elemnet) in the array. Otherwise undefined is returned.
• index: Contains all the utility functions mentioned here, encapsulated in an object for better access.
• letterPositions(sentence): Fucntions that returns the position(index) of each letter in the given sentece.
• map(array, callBack): Function that taken in an array and a callback function. Returns a new array of the elements that satisfy the callback function.
• middle(array): Function that takes in an array and returns the middle.
• tail(array): Function that takes in an array and returns the tail of the array (removes head).
• takeUntil(array, callBack): Function that takes in an array and a callback. pushes all items of array into into a new array, until the callback evalautes to true.
• without(array, itemsToRemove): Functions that takes in two arrays. the original array and an array containing the items to remove. Returns the new array with the removed items.
