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 Lotide:

npm install @ballsy/lotide

Require Lotide:

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

Call Lotide:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Strictly compares input array to the expected output array. Logs the pass or fail to the console.
• assertEqual(actual, expected): Stricly compares input primitive values to the expected output. Logs the pass or fail to the console.
• assertObjectsEqual(actual, expected): Stricly compares input primitive values to the expected output. Logs the pass or fail to the console.
• eqArrays(Arr1, Arr2): Strictly compares two input arrays. Returns true or false.
• eqObjects(object1, object2): Strictly compares two input objects. Returns true or false.
• countLetters(str): Takes and input string and returns the number of letters & characters, less the whitespace.
• countOnly(allItems, itemsToCount): Takes an input array and an object populated with the elements to be counted (if truthy) or not (if falsey).Returns an object with the results.
• findKey(object, callback): Takes an object and function to execute it. Searches for a key in the object that matches the conditions given and returns the first key name found that matches.
• findKeyByValue(obj, value): Takes an object and a value to search for. Searches for a key in the object that matches the specified value.
• flatten(source): Takes a source array with a nested array and returns a single "level" array. (Not recursive. Only a single level of nesting can be flattened at a time.)
• head(Arr): Takes an array and returns the element at the first index.
• letterPositions(str): Takes a string and returns an object with the index of each occurrence of each character in the string. Occurrence of whitespace is not returned.
• map(array, callback): Takes an array and a function to be executed on the array. Returns a new array with the results.
• middle(array): Takes an array and returns the value at the middle index position. Returns two values if the length of the array is even.
• tail(Arr): Takes an array and returns it without the element at the first index of the input array.
• takeUntil(array, callback): Takes an array and a function to be executed on it. Loops over the array and returns it as is until it hits the break condition of the callback.
• without(source, itemsToRemove): Takes a source array and array of unwanted items. Returns a new array with only those elements from the source array which are NOT present in the itemsToRemove array. Stricly compares the values between both arrays.
