LotideV2

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 @taomosquito/lotideV2

Require it:

const _ = require('@taomosquito/lotideV2');

Call it:

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

Documentation

The following functions are currently implemented:

• head(): returns the head of a source array that is passed in as a function argument.
• tail(): returns everything but the head of a source array that is passed in as a function argument.
• middle(): returns the middle element of a source array if odd length or middle two elements if even length.
• without(): returns a new array that excludes anything in the comparison array.
• takeUntil(): returns a new array that returns every element incrementally up until the condition is true.
• map(): iterates through an array and provides a modification to every element using a callback designed around unnamed callbacks since it is expecting a condition.
• letterPositions(): returns an object containing an array of indices based on where in a string a character occurs for each character in the string expects the string added as a parameter.
• flatten(): compresses a nested array 1 layer deep.
• findKey(): finds a key in an object passed in as a parameter when given a callback as a second parameter.
• findKeyByValue(): finds a key in an object passed in as a parameter when given a value as a second parameter.
• eqArrays(): takes in two arrays as arguments and checks if they are equal or not.
• eqObjects(): takes in two objects as arguments and checks if they are equal or not.
• countOnly(): takes in an array of items and an object of conditions and returns the amount of times that condition is true in the given array.
• countLetters(): returns an object containing each character in the string and a value equal the amount of times it exists in the string.
• assertEqual(): prints a stylized assertion to the console based on the equality of two values.
• assertArraysEqual(): prints a stylized assertion to the console based on the equality of two arrays.
• assertObjectsEqual(): prints a stylized assertion to the console based on the equality of two objects (this has a verbose trigger as an optional third argument expecting truthy to make verbose).
