@ndav/lotide v1.0.0

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 @ndav/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): outputs first element of an array
• tail(arr): outputs an array of elements except the first one
• eqArrays(arr1, arr2): checks if every element of 2 arrays match
• eqObjects(obj1, obj 2): checks if every key value pair of 2 objects match
• without(arr, itemsToRemove): filters specific items in array from another array
• middle(arr): returns an array of middle-most elements
• countOnly(obj, count): takes in a collection of items and returns count for specific subset of those items
• countLetters(str): returns an object representing count of each letter in a string
• letterPositions(str): returns an object representing indices of a string where each character is found
• findKeyByValue(obj, value): search the object and returns first key containing given value
• assertObjectsEqual(obj1, obj2): checks the equality of 2 arrays and prints corresponding message
• assertArraysEqual(arr1, arr2): checks the equality of 2 arrays and prints corresponding message
• assertEqual(actual, expected): checks the equality of 2 values and prints corresponding message
• map(arr, callback): returns a new array of first indices of input array strings
• takeUntil(arr, callback): slice an array from the beggining until specified condtition
• findKey(obj, callback): search for a key in a given obj which satisfies the provided condition
• flatten(arr): transfroms one-level-nested array to single-level array
