Clean Code: 7 tips to write clean functions
If it takes more than 3 seconds to understand what a function does, it's time to refactor it. The quality of your functions is inversely proportional to the time it takes to understand them.
Complex functions can lead to errors, make changes difficult, and slow down the onboarding process for new developers. Remember, code is read far more often than written, so investing time in writing clean functions is one of the best investments you can make in the long run.
Here are 7 tips on how I write clean functions:
Keep your functions small
Name your functions well
Limit the number of parameters
Reduce nesting with a return early
Write pure function with no side effects
Avoid boolean flag parameters
Use comments sparingly
We spend 10x more reading the code than writing it. Writing clean functions is one of the most powerful ways to produce readable code. Remember: Coding is not just telling the computer what to do. It's telling another programmer what you want the computer to do. Every line of code you write is a message to your fellow developers. Make it clear, concise, and compelling.

npm (Node Package Manager), is a command line tool to install, create, and share packages of JavaScript code written for Node.js. There are many open source packages available on npm, so before starting a project, take some time to explore so you don't end up recreating the wheel for things like working with dates or fetching data from an API.
In this course, you'll learn the basics of using npm, including how to work with the package.json and how to manage your installed dependencies.

Introduction to Advanced Node and Express Challenges
Authentication is the process or action of verifying the identity of a user or process. Up to this point you have not been able to create an app utilizing this key concept.
The most common and easiest way to use authentication middleware for Node.js is Passport. It is easy to learn, light-weight, and extremely flexible allowing for many strategies, which we will talk about in later challenges. In addition to authentication we will also look at template engines which allow for use of Pug and web sockets which allow for real time communication between all your clients and your server.
