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.

Install it:

npm install @arenritz/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): Returns the first element of an array.
• tail(arr): Returns the array without the head(first element).
• middle(arr): Returns the middle value of an array, if it's even the middle 2 numbers.
• without(arr1, arr2): Returns a new array which equals the element of the first - the second.
• takeUntil(arr, val): Iterates through each item of array and pushes them to a new array until it element of the array matches the value.
• assertEqual(actual, expected): Checks strickt equality between two values and console logs the result.
• eqArrays(arr1, arr2): Returns true or false if the arrays match.
• assertArraysEqual(arr1, arr2): Uses eqArrays to log if the arrays match.
• eqObjects(obj1, obj2): Returns true or false if the objects match.
• assertObjectsEqual(arr): Uses eqObjects to log if the objects match.
• findKey(obj, val): Scans 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.
• countOnly(arr, val): Returns how many times the value is found in the array.
• findKeyByValue(obj, val): Returns the object key which contains the passed value.
