@sydannyopal/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 @sydannyopal/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEquals(...): This function helps us test our code.
• head(...): This function returns the first item in the array.
• tail(...): This function returns the "tail" of an array: everything except for the first item (head) of the provided array.
• eqArrays(...): This function can compare two arrays for a perfect match
• assertArraysEqual(...): This function is for asserting that two arrays are equal.
• without(...): This function returns a subset of a given array, removing unwanted elements.
• middle(...): This function takes in an array and return the middle-most element(s) of the given array.
• countOnly(...): This function should take in a collection of items and return counts for a specific subset of those items.
• countLetters(...): This function takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• letterPositions(...): This function returns all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue(...): This function searches for a key on an object where its value matches a given value.
• eqObjects(...): This function takes in two objects and returns true or false, based on a perfect match.
• assertObjectsEqual(...): This function will help us easily test functions that return objects.
• Map(...): This function returns a new array based on the results of the callback function.
• takeUntil(...): This function will keep collecting items from a provided array until the callback provided returns a truthy value.
• findKey(...): This function takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value.
