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 @sabrina.yw/lotide

Require it:

const _ = require('@sabrina.yw/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Returns first element of given array, or undefined if empty array
• tail(array): Returns all elements of array except first. Arrays with one element or an empty array return an empty array.
• middle(array): Returns the middle value(s) of given array, returns empty array if given array of length 1 or 2
• countLetters(string): Takes sentence as string, returns count of each of the letters in sentence (as object)
• countOnly(array, object): Returns an object containing counts of everything that input object lists
• findKey(object, callback): Returns first key in object for which callback returns a truthy value. Return undefined if no key found.
• findKeyByValue(object, value): Takes object and value, scans object and returns first key which contains given value. Return undefined if no key with given value found.
• flatten(array): Returns flattened single-level array
• letterPositions(string): Returns all indices in string where each character is found (as object)
• map(array, callback): Returns new array based on results of callback function
• takeUntil(array, callback): Returns slice of given array with elements taken from beginning until callback returns truthy value
• without(array, element): Returns subset of given array, removing unwanted elements
• eqArrays(array1, array2): Returns true if arrays are the same
• eqObjects(obj1, obj2): Returns true if objects are the same
