@dyoung4747/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 @dyoung4747/lotide

Require it:

const _ = require('@udyoung4747/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Determines if actual array equals the expected array.
• assertEqual(actual, expected): Determines if actual value equals expected value.
• assertObjectsEqual(actual, expected): Determines if actual object equals expected object.
• countLetters(str): Takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(arr, obj): Takes in a collection of items and return counts for a specific subset of those items.
• eqArrays(arr1, arr2): Determines if two arrays are equal.
• eqObjects(obj1, obj2): Determines two objects are equal.
• findKey(obj, callback): Takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(obj, value): Searches for a key on an object where its value matches a given value.
• flatten(arr): Given an array with other arrays nested inside, it will flatten the array into a single-level array.
• head(arr): Takes in an array and returns the first element in the array.
• letterPositions(str): Takes in a string and will return all the indices (zero-based positions) where each character is found.
• map(arr, callback): Takes in an array and callback, and returns a new array based on the results of the callback function.
• middle(arr): Takes in an array and returns the middle element if array length is an odd number, and middle two elements if array length is even.
• tail(arr): Takes in an array and returns an array without the first element.
• takeUntil(arr, callback): Takes in an array and callback, and returns a "slice of the array with elements taken from the beginning."
• without(sourceArr, itemsToRemoveArr): This function takes in a source array and an itemsToRemove array and returns a new array with only those elements from source that are not present in the itemsToRemove array.
