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 @nofarziv/lotide
Require it:
const _ = require('@nofarziv/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
head(...): a function which returns the first item in the array. -
tail(...): a function which returns the "tail" of an array: everything except for the first item (head) of the provided array. -
middle(...): a function which takes in an array and return the middle-most element(s) of the given array. -
assertArraysEqual(...): a function for asserting that two arrays are equal -
assertEqual(...): a function which compares two values it takes in and print out a message telling us if they match or not. -
eqArrays(...): a function that can compare two arrays for a perfect match. -
assertObjectsEqual(...): a function which takes in two objects and console.log an appropriate message to the console. -
countLetters(...): a function which takes in a sentence (as a string) and then return a count of each of the letters in that sentence. -
findKey(...): a function which takes in an object and a callback. It scans the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined. -
countOnly(...): a function which when given an array and an object. It will return an object containing counts of everything that the input object listed. -
eqObjects(...): a function which takes in two objects and returns true or false, based on a perfect match. -
findKeyByValue(...): a function which takes in an object and a value. It scans the object and return the first key which contains the given value. If no key with that given value is found, then it returns undefined. -
letterPositions(...): a function which returns all the indices (zero-based positions) in the string where each character is found. -
takeUntil(...): a function which keeps collecting items from a provided array until the callback provided returns a truthy value. -
without(...): a function which returns a subset of a given array, removing unwanted elements.
