Lotide

A mini clone of the Lodash library.

Purpose

Lotide folder contains smaller functions that we build to exercise our programming chops throughout the first four weeks at LHL.

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 Ashton Ferguson as part of my learnings at Lighthouse Labs.

Usage

Install it: npm install @devferguson/lotide

Require it: const _ = require('@devferguson/lotide');

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

Documentation

The following functions are currently implemented:

• assertEqual - a function that takes in 2 values and returns true if they are equal and false otherwise.

• assertArraysEqual - a function that prints an appropriate message after comparing the two arrays.

• assertObjectsEqual - a function that takes in 2 objects and returns true if they are equal and false otherwise.

• countLetters - a function that takes in a sentence and returns a count of each of the letters in the sentence.

• countOnly - a function that takes in a collection of items and returns a specific subset of those items.

• eqArrays - a function that takes in 2 arrays and returns true if the arrays are equal and false otherwise.

• eqObjects - a function that takes in 2 objects and return true if they are equal and false otherwise.

• findKey - a function that takes in an object and callback and returns the first key that meets the criteria specified in callback.

• findKeyByValue - a function that takes in an object and a value and returns the first key that corresponds to that value.

• Flatten - a function that takes in an array that contains elements including nested array of elements and returns a flattened version of the array.

• Head - a function that takes in an array and returns the first element in the array. index

• letterPosition - a function that takes in a string and returns all indices of letter positions in the string.

• Map - a function that takes in an array and a callback and returns a new array based on the results of the callback on each item in the array.

• Middle -a function that takes in an array and returns the middle most element of the array.

• Tail - A function that takes in an array and returns everything except the first element of the array.

• takeUntil - a function that takes in an array and callback and returns a slice of the array based on the criteria specified in the callback.

• Without - a function that takes in a source array and an itemsToRemove arrays and returns only the items from the source array that are not in the itemsToRemove array.
