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 stufromnorthvan/lotide

Require it:

const _ = require('stufromnorthvan/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array) : returns index 0, or first value, of an array.
• tail(array) : returns array without index 0, or first value.
• middle(array) : returns middle value of an array. if array is even-numbered, returns 2 middle values.
• assertArraysEqual(array1, array2): returns true if arrays equal, false if not.
• assertEqual(value1, value2): returns true if values are equal, false if not.
• assertObjectsEqual(object1, object2) : returns true if objects are equal, false if they are not.
• countLetter(string): counts letters in a string. string can be given an index value of letter to count one particular letter.
• countOnly(array1, argument): loops through an array and counts only instances of the argument. argument can be an object with booleans to satisfy multiple conditions.
• eqArrays(array1, array2): returns true if arrays are equal, false if they are not.
• eqObjects(object1, object2): returns true if objects are equal, false if they are not.
• findKey(object, callback): finds key with callback function
• findKeyByValue(object, value): finds key in object based off object value.
• letterPositions(string): shows the index position(s) of letters in a given string. formula can be given an index value to count one particular letter.
• map(array, callback): edits all elements of an array with a callback function.
• takeUntil(array, callback): goes through elements of an array until a given character, specified by callback function.
• without(array, itemsToRemove): goes through an array and removes itemsToRemove.
