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 @username/lotide

Require it:

const _ = require('@johnny-prencipe/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: gives highly visible feedback when passed 2 arrays, about whether they are equal or not.
• assertEqual: gives highly visible feedback when passed pieces of primitive data, about whether they are equal or not.
• assertObjectsEqual: gives highly visible feedback when passed pieces of object data about whether they are equal or not.
• countLetters: counts the non-space characters of a string passed as an argument.
• countOnly: counts how many times a certain piece of data appears in an array
• eqArrays: returns true or false when passed 2 arrays, based on whether they are equal
• eqObjects: returns true or false when passed 2 objects, based on whether they are equal
• findKey: returns the key of an object based on the result of a callback function
• findKeyByValue: returns the key of an object based on the value
• flatten: returns a flattened version of nested arrays
• head: returns the first index of an array
• letterPositions: takes 2 arguments of strings, one sentence and one letter. returns the position of the letter in the sentence.
• map: takes an array argument and a callback function, returns a new array based on the evaluation of the callback function on each item.
• middle: returns the one (if odd) or 2 (if even) middle indeces of an array
• tail: returns all but the first index in an array
• takeUntil: takes an array argument and a callback function, executes the callback on each item in the array and returns a new array consisting of every item up until the point at which the callback funcion evalutated to true.
• without: takes 2 arguments, an array and an element, and returns a new array with every element other than the one specified in the arguments.
