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 @ill-eagle/lotide

Require it:

const _ = require('@ill-eagle/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Asserts whether or not two arrays are equal, using the eqArray function.

• assertEqual(actual, expected): Asserts whether or not two values are equal.

• assertObjectsEqual(object1, object2): Asserts whether two objects are equal by comparing their properties using the eqObjects function.

• countLetters(string): Counts the number of letters in a string, excluding spaces.

• countOnly(allItemsArray, itemsToCount): Counts the number of instances of a given value within an array.

• eqArray(arr1, arr2): Returns a boolean value if two arrays are equal or not.

• eqObjects(object1, object2): Returns a boolean value of whether or not two objects are equal.

• findByKeyValue(object, value): Finds the value of a key within a given object.

• findKey(object, function): Returns a key(s) within an object that aligns with the given callback function.

• flatten(array): Flattens an array one level, removing nested arrays.

• head(array): Returns the first item in an array.

• letterPositions(string): Returns the indices where each character is found in a given string.

• map(array, callback): Returns an array of each element in the array as modified by the callback function.

• middle(array): Returns the middle value in an array for oddly-numbered, and the middle two digits for evenly-numbered.

• tail(array): Returns the final element in an array.

• takeUntil(array, callback): Returns elements of the array until a condition specified by the callback function is met.

• without(source, toRemove): Returns the source array with the desired element removed.
