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.

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(): Function that accepts two arrays as parameters and prints an appropriate message to the console telling us if they match or not.
• assertEqual(): Function that compares the two values passed to it and prints a message indicating whether they match or not.
• assertObjectsEqual(): Function that accepts two objects as parameters and prints a message to the console telling us if they match or not.
• countLetters(): Function that returns an object where each property is a unique character whose value is the number of times that character occurred.
• countOnly(): Function that takes in a collection of items and returns the count for a specific item.
• eqArrays(): Function that takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(): Function that takes in two objects and returns true or false, based on a perfect match.
• findKey(): Function takes in an object and a callback function. It will iterate through the object and return the first key for which the callback returns a truthy value. If no key mathces, then it'll return undefined.
• findKeyByValue(): Function that takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• flatten(): Function that accepts an array of arrays as a parameter and returns a flattened (single) array.
• head(): Function that returns the first item in an array.
• letterPositions(): Function that returns the indices of the string where the respective character is found.
• map(): Function that returns a new array based on the results of the callback function.
• middle(): Function that takes in an array and returns the middle-most element of an odd numbered array or the two middle-most elements of an even array.
• tail(): Function that returns the array without the first element.
• takeUntil(): Function that returns a selected amount of elements taken from the beginning, until the callback returns a truthy value.
• without(): Function that returns a new array, removing the unwanted elements from the given array.
