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 @joshgrant5/lotide

Require it:

const _ = require('@joshgrant5/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the head of an array (first item).
• tail(array): returns the tail of an array (every item following the first item).
• middle(array): returns the middle item of an array (returns middle 2 items if length of array is even). (returns an empty array if length of array < 3).
• assertEqual(actual, expected): logs passing or failing message for actual === expected.
• eqArrays(array1, array2): returns boolean for array1 === array2 (perfect match).
• assertArraysEqual(array1, array2): logs passing or failing message for array1 === array2.
• eqObjects(object1, object2): returns boolean for object1 === object2 (perfect match).
• assertObjectsEqual(object1, object2): logs passing or failing message for object1 === object2.
• countOnly(allItems, itemsToCount): returns object for the count of each item specified by itemsToCount (an object specifiying what to count).
• countLetters(sentence): returns an object for the count of each letter in the sentence.
• findKey(object, callback): scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue(object, value): scans the object and return the first key which contains the given value.
• flatten(array): returns a "flattened" array // => flatten([1, 2, 3, 4, 5); // => 1, 2, 3, 4, 5.
• letterPositions(sentence): returns an object of all the indices in the string where each character is found.
• map(array, callback): takes in two arguments: (1. An array to map, 2. A callback function). Returns a new array based on the results of the callback function.
• takeUntil(array, callback): Collecs items from a provided array until the callback provided returns a truthy value. Returns an array of the collected items.
• without(source, itemsToRemove): returns a new array with the specified item(s) removed.
