00:30 - MongoDB Installation
01:10 - Serialize Function - passport.serializeUser()
Passport will call this to serialize the user to the session whenever you login a user with req.login(), or whenever a user is authenticated via passport.authenticate(). The function you pass in should call done(null, serializedUser). What this is going to do is set req.session.passport.user = serializedUser.

————————————————————————————————————
Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser.

Express.js, or simply Express, is a web application framework for Node.js. It is designed for building web applications and APIs. It has been called the de facto standard server framework for Node.js. Express runs between the server created by Node.js and the frontend pages of a web application. Express also handles an application's routing.

freeCodeCamp (also referred to as “Free Code Camp”) is a non-profit organization that consists of an interactive learning web platform, an online community forum, chat rooms, online publications and local organizations that intend to make learning web development accessible to anyone. Beginning with tutorials that introduce students to HTML, CSS and JavaScript, students progress to project assignments that they complete either alone or in pairs. Upon completion of all project tasks, students are partnered with other nonprofits to build web applications, giving the students practical development experience.
