@wahab110/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 @wahab110/lotide

Require it:

const _ = require('@wahab110/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head: returns the first element in an array.
• middle: returns the middle most elements of an array above a length of 2. If array length is even it returns both sides of the middle.
• tail: returns everything but the first item in an array.
• assertEqual: compares 2 primitive data types together and console logs whether or not they match.
• assertArraysEqual: similar to eqArrays, however this will log to the console whether they match or not, rather than returning true or false.
• countLetters: takes in a sentence as a string and returns a count of each letter within that sentence.
• countOnly: is given an array and object as arguments. Returns a new object containing the count of everything in the array that the object argument listed.
• eqArrays: takes in two arrays and returns true or false if they are the same.
• findKeyByValue: takes in an object and value. Returns the first key which contains the given value, and if no key with the given value is found it returns undefined.
• letterPositions: returns all the indices in the string argument where each character is found.
• without: intakes two arrays as arguments. Second array informs which elements from the first array you no longer want, and returns the remainder as a new array.
• assertObjectsEqual: similar to eqObjects, but logs a statement stating whether they match or not rather than returning true or false.
• eqObjects: takes in two objects as arguments. Returns true or false depending on whether they're the same or not.
• findKey: takes in an object and a callback function. Will return the first key for which the callback function returns a truthy value and if no key is found then it returns undefined.
• map: takes in an array to map and a callback function. Will return a new array based on the results of the callback function.
• takeUntil: takes in an array to work with and a callback function. Loops through the array and returns the values as a singular array until the callback function is truthy.
