JavaScript Runtimes

Rhino

Rhino is an open-source JavaScript engine written in Java, developed by Mozilla, that allows JavaScript code to be executed within Java applications. It enables developers to embed JavaScript functionality into Java programs, providing a bridge between the two languages for scripting, automation, and dynamic behavior. It is commonly used for tasks like server-side scripting, testing, and extending Java applications with JavaScript-based logic.

Also known as: Mozilla Rhino, Rhino JS, Rhino JavaScript Engine, Rhino-Java, JS in Java

🧊Why learn Rhino?

Developers should learn Rhino when working on Java projects that require JavaScript integration, such as building plugins, automating tasks with scripts, or creating dynamic web applications where Java and JavaScript need to interact. It is particularly useful in environments like Apache Sling or older Java-based systems where embedded scripting is needed for customization or rapid prototyping without recompiling Java code.

Other JavaScript Runtimes

.env is a file format and tool used to store environment variables, which are key-value pairs that configure application settings like API keys, database URLs, and other sensitive or environment-specific data. It allows developers to separate configuration from code, making applications more secure and portable across different environments (e.g., development, testing, production). Tools like dotenv in Node.js or python-dotenv in Python parse .env files to load these variables into the application's environment at runtime.

.htaccess (Hypertext Access) is a configuration file used on Apache web servers to control directory-level settings, such as URL redirection, access control, and performance optimizations. It allows developers to override global server configurations for specific directories without modifying the main server configuration files. This file is commonly used for tasks like enabling HTTPS, blocking IP addresses, or setting custom error pages.

2D Drafting is the process of creating technical drawings and schematics in two dimensions using specialized software, primarily for engineering, architecture, and manufacturing design. It involves producing precise, scaled representations of objects, components, or structures with detailed annotations, dimensions, and symbols to communicate design intent and specifications. This skill is foundational for translating conceptual ideas into actionable plans for construction, fabrication, or analysis.

2D Drafting Tools

2D drafting tools are software applications used to create precise technical drawings, schematics, and blueprints in two dimensions. They enable engineers, architects, and designers to produce detailed plans with accurate measurements, annotations, and geometric shapes. These tools are essential for documenting designs before moving to 3D modeling or physical construction.

2D Drawing Review

2D Drawing Review refers to the process and software tools used to examine, annotate, and collaborate on two-dimensional technical drawings, such as blueprints, schematics, or CAD designs. It involves checking for accuracy, compliance with standards, and identifying errors or improvements in engineering, architecture, or manufacturing contexts. Tools for this purpose often include features like markup, version control, and real-time collaboration to streamline review cycles.

2D Graphics Software

2D graphics software refers to computer programs used to create, edit, and manipulate two-dimensional digital images, illustrations, and designs. These tools provide features like drawing, painting, vector graphics, image editing, and layout design for applications such as digital art, UI/UX design, game sprites, and print media. They range from professional suites like Adobe Photoshop to free alternatives like GIMP and Inkscape.
