Functions in C++
Functions allow us to define a block of code to perform a particular action. We can make use of functions, arguments and returns to avoid issues with code duplication.

C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language, or "C with Classes". 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).

windows-xp-basic-review
I KNOW IT CAME OUT IN 2001
[Welcome to my first review! I will be reviewing windows xp. Please don't be too harsh as this is my first time doing this.]
Windows XP is an operating system produced by Microsoft for use on personal computers, including home and business desktops, laptops and media centers. First released to computer manufacturers on August 24, 2001, it is the second most popular version of Windows, based on installed user base. The name "XP" is short for "eXPerience", highlighting the enhanced user experience.

Content-Security-Policy is the name of a HTTP response header that modern browsers use to enhance the security of the document (or web page). The Content-Security-Policy header allows you to restrict how resources such as JavaScript, CSS, or pretty much anything that the browser loads.

HelmetJS is a type of middleware for Express-based applications that automatically sets HTTP headers to prevent sensitive information from unintentionally being passed between the server and client. While HelmetJS does not account for all situations, it does include support for common ones like Content Security Policy, XSS Filtering, and HTTP Strict Transport Security, among others. HelmetJS can be installed on an Express project from npm, after which each layer of protection can be configured to best fit the project.

11-display-shapes-with-svg-data
We look at the shape elements we can create with SVG. Rectangles can be created with the rect tags and providing x and y coordinates to position it, and width and height values to adjust its size. It's important to note that the position values dictate where the top-left corner of the rectangle appears, not the center.
Link to challenge : https://www.freecodecamp.org/learn/data-visualization/data-visualization-with-d3/display-shapes-with-svg
Concepts:
Rect
The rect element is used to create a rectangle and variations of a rectangle shape. The width and height attributes define the height and the width of the rectangle.
https://www.w3schools.com/graphics/svg_rect.asp
SVG Shapes: https://www.w3.org/TR/SVG2/shapes.html
SVG
Scalable Vector Graphics is an Extensible Markup Language-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images and their behaviors are defined in XML text files.
https://www.w3schools.com/graphics/svg_intro.asp
selection.style(name[, value[, priority]])
If a value is specified, sets the style property with the specified name to the specified value on the selected elements and returns this selection. If the value is a constant, then all elements are given the same style property value; otherwise, if the value is a function, it is evaluated for each selected element, in order, being passed the current datum (d), the current index (i), and the current group (nodes), with this as the current DOM element (nodes[i]). The function’s return value is then used to set each element’s style property. A null value will remove the style property. An optional priority may also be specified, either as null or the string important (without the exclamation point).
If a value is not specified, returns the current value of the specified style property for the first (non-null) element in the selection. The current value is defined as the element’s inline value, if present, and otherwise its computed value. Accessing the current style value is generally useful only if you know the selection contains exactly one element.
https://github.com/d3/d3-selection/blob/v1.4.1/README.md#selection_style
selection.attr(name[, value])
If a value is specified, sets the attribute with the specified name to the specified value on the selected elements and returns this selection. If the value is a constant, all elements are given the same attribute value; otherwise, if the value is a function, it is evaluated for each selected element, in order, being passed the current datum (d), the current index (i), and the current group (nodes), with this as the current DOM element (nodes[i]).

npm requires that all packages published confrom to Semantic Versioning, an industry standard. They take the form major.minor.patch, where major signifies non-backwards compatible API changes, minor feature updates and patch small bugfixes.

Concepts:
Semantic Versioning
Given a version number MAJOR.MINOR.PATCH, increment the:
- MAJOR version when you make incompatible API changes,
- MINOR version when you add functionality in a backwards compatible manner, and
- PATCH version when you make backwards compatible bug fixes.
https://semver.org/
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.

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.

Project Euler (named after Leonhard Euler) is a website dedicated to a series of computational problems intended to be solved with computer programs. The project attracts adults and students interested in mathematics and computer programming. Since its creation in 2001 by Colin Hughes, Project Euler has gained notability and popularity worldwide. It includes over 700 problems, with a new one added once every one or two weeks. Problems are of varying difficulty, but each is solvable in less than a minute of CPU time using an efficient algorithm on a modestly powered computer. As of 5 April 2020, Project Euler has more than 1,000,000 users, from all over the world, who have solved at least one problem.

To dynamically changed styles, we can use a function as the value argument in the style method, which can take in an item from the data set and return a value based on that.

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.
