@gulsemin/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 @gulsemin/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: Returns pass or fail by comparing actual and expected arrays.
• assertEqual: Prints pass or fail by comparing actual and expected values.
• assertObjectsEqual: Returns pass or fail by comparing actual and expected objects.
• countLetters: The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly: This function should take in a collection of items and return counts for a specific subset of those items
• eqArrays: Prints arrays are equal or not by comparing two arrays.
• eqObjects: will take in two objects and returns true or false, based on a perfect match.
• findKey: Accepts two arguments - an object and a callback.Returns the first key for which the callback equals a truthy value after iterating through the object.
• findKeyByValue: takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• flatten: Returns a new array by merging two arrays that are nested.
• head: Returns the first element of an array.
• letterPositions: will return all the indices (zero-based positions) in the string where each character is found.
• map: Returns the first letter of each element in an array.
• middle: Return the middle-most element(s) of the given array.
• tail: Returns an array after removing the first element.
• takeUntil: Accepts two arguments - an array and callback function. Returns a new array of items occuring until the end point that is specified by the callback function.
• without: Accepts two arguments - an array and items to remove. Returns a new array that excludes the items that are removed.
