@ruby.zhuang/lotide v1.0.1

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 @ruby.zhuang/lotide

Require it:

const _ = require('@ruby.zhuang/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(string): takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
• countOnly(array, object): takes in an array of items and then returns counts for a specific subset of those items.
• eqArrays(array1, array2): two arrays and then returns true or false, based on a perfect match.
• eqObjects(object1, object2): takes in two objects and then returns true or false, based on a perfect match.
• findKey(ojbect, vlaue): takes in an object and a value and then returns the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• findKeyValue(object, callback): takes in an object and a callback and then returns the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• flatten(array): takes in an array containing elements including nested arrays of elements, and then returns a "flattened" version of the array.
• head(array): takes in an array and then returns the first item in the array.
• letterPositions(string): takes in a sentence and then returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): takes in an array and callback and then returns a new array based on the results of the callback function.
• middle(array): takes in an array and then returns the middle-most element(s) of the given array.
• tail(array): takes in an array and then returns the "tail" of an array - everything except for the first item (head) of the provided array.
• takeUntil(array, callback): takes in an array and callback function and then returns a slice of the array with elements taken from the beginning until the callback provided returns a truthy value.
• without(source, itemsToRemove): takes in a source array and a itemsToRemove array and then returns a subset of a given array, removing unwanted elements.
