@antosha-85/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 @antosha-85/lotide

Require it:

const _ = require('@antosha-85/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• function1(head): returns the first item in the array
• function2(tail): returns the "tail" of an array: everything except for the first item (head) of the provided array
• function3(middle): will take in an array and return the middle-most element(s) of the given array.
• function4(assertEqual): description
• function5(assertObjectEqual): Implement assertObjectsEqual which will take in two objects and console.log an appropriate message to the console
• function6(countLetters): The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence
• function7(countOnly): will return an object containing counts of everything that the input object listed.
• function8(eqArrays): compares two arrays for a perfect match
• function9(eqObjects): will take in two objects and returns true or false, based on a perfect match.
• function10(findKey): 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. If no key is found, then it should return undefined
• function11(findKeyByValue): which 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
• function12(flatten): will take in an array of arrays and return a "flattened" version of the array.
• function13(letterPositions): new function letterPositions which will return all the indices (zero-based positions) in the string where each character is found
• function14(map): The map function will return a new array based on the results of the callback function
• function15(takeUntil): The function will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value
• function16(without): will return a subset of a given array, removing unwanted elements
• function17(assertArrayEqual): assertion function will make use of your eqArrays function for array comparison.
