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 @username/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): asserts whether the inputted arrays are equal or not
• assertEqual(actual, expected): asserts whether actual and expected are equal or not
• assertObjectsEqual(object1, object2): asserts wether the inputted objects are equal or not
• countLetters(string): returns an object where key-value pairs represent the characters present in the string, and the count of how many times they are included. spaces are excluded
• countOnly(array, object): returns an object indicating how many times counted values occur in the input array
• eqArrays(array1, array2): returns true if arrays are equal, false if they are not equal
• eqObjects(object1, object2): returns true if objects are equal, false if they are not equal
• findKey(object, callack): returns the first key that meets callback condition
• findKeyByValue(object, soughtValue): returns first key whose value equals soughtValue
• flatten(array): returns flatten nested arrays up to one nesting-deep
• head(array): returns the value at array's first index
• letterPositions(sentence) : returns objects indicating the indices of each unique character in a string sentence. spaces are excluded
• map(array, callback): iterates through array applying callback function to each element, returns array of result
• middle(array): if length of array is odd, returns middle value, if length of array is even, returns middle two values, if array contains 2 or fewer elements, return an empty array
• tail(array): returns new array containing all but the first value of input array
• takeUntil(array, callback): returns values in array up until a value satisfies the callback condition, non-inclusive
• without(array, itemsToRemove): return modded array of input array, with items in itemsToRemove removed
