Definitions:
- JavaScript: A high-level, interpreted programming language that is a core technology of the World Wide Web. JavaScript is used to create interactive effects within web browsers, enabling dynamic and responsive user interfaces. It is widely used in frontend development, but it also has server-side capabilities with frameworks like Node.js.
- Jupyter Notebook: An open-source web application that allows you to create and share documents that contain live code, equations, visualizations, and narrative text. Jupyter Notebooks are widely used in data science, machine learning, and scientific computing. They support multiple programming languages, including Python, R, and Julia, and enable interactive data analysis and exploration.
- JSON (JavaScript Object Notation): A lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. JSON is often used for transmitting structured data between a server and a web application. It is language-independent and is widely supported by various programming languages and platforms.
- Jenkins: An open-source automation server that enables developers to build, test, and deploy software continuously. Jenkins supports continuous integration and continuous deployment (CI/CD) pipelines, automating the software development lifecycle. It integrates with various tools and platforms, including version control systems, build tools, and deployment environments.
- Jira: A project management tool developed by Atlassian that is used for tracking issues and project management. Jira is widely used by software development teams for agile project management, bug tracking, and task management. It supports various workflows and integrations, enabling teams to collaborate effectively and manage their projects efficiently.
- JIT (Just-In-Time) Compilation: A method of executing computer code that involves compilation during execution rather than before execution. JIT compilation improves performance by compiling bytecode into machine code at runtime, reducing the overhead of interpretation. This technique is used in various programming environments, including Java and .NET.
- JQuery: A fast, small, and feature-rich JavaScript library that simplifies HTML document traversal, event handling, animating, and Ajax interactions. JQuery makes it easier to write JavaScript code that interacts with the DOM, enabling developers to create dynamic and interactive web applications quickly and efficiently.
- JDBC (Java Database Connectivity): An application programming interface (API) for the programming language Java, which defines how a client may access a database. JDBC provides methods for querying and updating data in a database, enabling Java applications to interact with various database management systems.
- Java Virtual Machine (JVM): A platform-independent execution environment that converts Java bytecode into machine language and executes it. The JVM enables Java applications to run on any device or operating system that supports the JVM, providing cross-platform compatibility. It is a cornerstone of the Java ecosystem and supports various programming languages beyond Java.
- JUnit: A unit testing framework for the Java programming language. JUnit is widely used for writing and running repeatable tests, enabling developers to test individual units of their code. It supports test-driven development (TDD) and is integrated with various development tools and environments.
- JavaServer Pages (JSP): A technology that helps software developers create dynamically generated web pages based on HTML, XML, and other document types. JSP allows Java code and certain predefined actions to be embedded into static content. It is used to generate dynamic content for web applications, enabling the creation of interactive and data-driven websites.
