@x_c_li/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 @x_c_li/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• without(sourceArray, itemsToRemove) : returns new array without specified items (itemsToRemove)
• takeUntil(array, callback): keep collecting items from provided array until callback provided returns truthy value
• tail(list): returns everything but the first item in a list
• head(list): only returns the first thing in that list
• flatten(nestedArray): takes in an array with a nested array of elements and returns a flattened version of the array
• middle(array): returns the middle value, but for even length array, returns two values for middle
• map(array, callback): returns a new array based on the results of the callback function
• letterPositions(sentence): return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue(objectName, val): scans object and return first key which contains given value, if no key w given value is found, return undefined
• findKey(thing, callback): get truthy if callback works, undefined if callback doesn't work
• eqObjects(object1, object2): returns whether the two objects are equal
• eqArrays(array1, array2): returns whether the two arrays are equal
• countOnly(allItems, itemsToCount):take in collection of items (strings) and return counts for a specific subset of those items --won't count everything, will return an object with the stats
• countLetters(sentence): returns object with a count of how many times a letter appeared in a string
• assertObjectsEqual(): uses eqObjects to log whether two object key value pairs are equal or not
• assertEqual(actual, expected): console.logs whether two (non-array or object) values are equal or not. Useful for testing.
• assertArraysEqual(actual,expected): uses eqArrays to see if console.log whether two arrays are equal or not. Useful for testing.
• swapper(key1, object1, key2, object2): swaps object 1 key 1 into object 2 key 2, and puts object 2 key 2 into object 1 key 1
