@luanateixeira148/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 @luanateixeira148/lotide

Require it:

const _ = require('@luanateixeira148/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): takes two arrays, compares them, and print out a message telling us if they match or not.
• assertEqual(actual, expected): takes two primitive values, compares them, and print out a message telling us if they match or not.
• assertObjectsEqual(actual, expected): takes two objects, compares them, and print out a message telling us if they match or not.
• countLetters(str): takes in a sentence (as a string) and returns a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): takes an array and an object, returns an object containing counts of everything that the input object listed.
• eqArrays(arr1, arr2): takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(object1, object2): takes in two objects and returns true or false, based on a perfect match.
• findKey(obj, callback): takes in an object and a callback. Returns the first key for which the callback returns a truthy value.
• findKeyByValue(obj, val): takes in an object and a value, and returns the first key that contains the given value.
• head(arr): takes in one array and returns its "head" (the first element from the array).
• letterPositions(setence): takes in a string and returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): takes in an array to map and a callback function. Returns a new array based on the results of the callback function.
• middle(arr): takes in an array and return the middle-most element(s) of the given array.
• tail(arr): takes in one array and returns its "tail" (every element except the head (first element) of the array) as a new array.
• takeUntil(array, callback): keeps collecting items from a provided array until the callback provided returns a truthy value.
• without(source, itemsToRemove): return a subset of a given array, removing unwanted elements.
