@ethanloewen/lotide v1.0.0

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 @ethanloewen/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Returns the first element in an array.
• tail(array): Returns everything expect the first element.
• middle(array): Returns the middle element of an array. If the length is even it will return the middle two elements.
• assertEqual(actual, expected): Checks if an outcome is what was expected.
• eqArrays(array1, array2): Checks if two arrays are equal.
• assertArraysEqual(actual, expected): Checks if a resulting array is what was expected.
• eqObjects(object1, object2): Checks if two objects are equal.
• assertObjectsEqual(actual, expected): Checks if a resulting object is what was expected.
• countLetters(string): Returns an object with the count of each letter in the string.
• countOnly(array, object): Returns an object with the count of each item from your input object. Items will only be counted if they are 'true' in the input object;
• findKey(object, callback): Scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(object, value): Returns the first key that contains the given value.
• flatten(array): Returns a flattened version of the array (removes 1 level of nested arrays).
• letterPositions(string): Retuns an object of the indices in a string where each character is found.
• map(array, callback): Returns an array modified by the callback function, where the callback function is called on each element in the input array.
• takeUntil(array, callback): Runs a callback function on each element of the input array until a truthy value is met.
• without(array1, array2): Removes the items in array2 from array1 and returns the modified array.
