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.

Install it:

npm install @cangoman/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(string): returns an object with the count of every character in the string.
• countOnly(allItems, itemsToCount): for an array allItems returns the count of elements set to true in itemsToCount.
• eqArrays(array1, array1): returns true if arrays are equal.
• eqObjects(object1, object2): returns true if objects are equal.
• findKey(object, callback) returns the first key in object for which the callback returns a truthy value.
• findKeyByValue(object, value): returns the first key which contains the given value. If no key is found, returns undefined.
• flatten(array) returns a flattened version of array. Uses recursion to deal with unknown levels of nesting.
• head(array): returns the first element (head) of an array. Returns an empty array if array is empty. Returns undefined if array is not an array.
• letterPositions(string): returns an object with the characters of the string as keys, and an array for each specifying their position in string.
• map(array, callback): returns a new array based on the results of the callback function.
• middle(array): returns the an array with the middle element of array if array.length is odd or the middle 2 elements if array.length is even.
• tail(array): returns an array consisting of all but the first element of array. Returns an empty array if array is empty.
• takeUntil(array, callback): Returns an array with the elements of the array from the beginnig until the callback returns a truthy value.
• without(array, itemsToRemove): returns an array with the elements of the original array, minus the elements included in itemsToRemove
