We have to create a Schema and a Model before we can write to the database. A Scheme defines a set of properties and types that our records will have. We can then use the Schema to create a 'Model' which can represent a real life entity like a Person.

Each schema maps to a MongoDB collection and defines the shape of the documents within that collection. You construct one, giving an object with key value pairs with properties and types the collection should have. https://mongoosejs.com/docs/guide.html Model Models are fancy constructors compiled from Schema definitions. An instance of a model is called a document. Models are responsible for creating and reading documents from the underlying MongoDB database. https://mongoosejs.com/docs/models.html mongoose.model() When you call mongoose.model() on a schema, Mongoose compiles a model for you. The first argument is the singular name of the collection your model is for. Mongoose automatically looks for the plural, lowercased version of your model name. https://mongoosejs.com/docs/models.html#compiling  -————————————————————————————————————- MongoDB is a cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas. MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License (SSPL). Mongoose is an Object Data Modeling (ODM) library for MongoDB and Node.js. It manages relationships between data, provides schema validation, and is used to translate between objects in code and the representation of those objects in MongoDB. 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.

You must add a 'version' key to every npm package, specifying the version number as a string.

The name and version together form an identifier that is assumed to be completely unique. Changes to the package should come along with changes to the version. If you don’t plan to publish your package, the name and version fields are optional. https://docs.npmjs.com/files/package.json#version package.json All npm packages contain a file, usually in the project root, called package.json - this file holds various metadata relevant to the project. This file is used to give information to npm that allows it to identify the project as well as handle the project's dependencies. It can also contain other metadata such as a project description, the version of the project in a particular distribution, license information, even configuration data - all of which can be vital to both npm and to the end users of the package. The package.json file is normally located at the root directory of a Node.js project. https://nodejs.org/en/knowledge/getting-started/npm/what-is-the-file-package-json/ -————————————————————————————————————- The Node Package Manager (npm) is a command-line tool used by developers to share and control modules (or packages) of JavaScript code written for use with Node.js. 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.

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.

C++ converts floats and doubles into IEEE 754 binary representations and stores these into memory. In the case of a float, 4 bytes are stored.

The language has expanded significantly over time, and modern C++ now has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Oracle, and IBM, so it is available on many platforms. C++ was designed with a bias toward system programming and embedded, resource-constrained software and large systems, with performance, efficiency, and flexibility of use as its design highlights. C++ has also been found useful in many other contexts, with key strengths being software infrastructure and resource-constrained applications, including desktop applications, video games, servers (e.g. e-commerce, Web search, or SQL servers), and performance-critical applications (e.g. telephone switches or space probes).
