Comparison of the programming languages Java and JavaScript with regard to their syntax, intended uses, execution and typing.Java vs. JavaScript: A Comparison1. Basic properties- Java: - Type: Java is an object-oriented programming language. - Development: Developed by Sun Microsystems (now part of Oracle) and first released in 1995. - Platform: Java is a platform-independent language that can run on different platforms through the Java Virtual Machine (JVM). A Java program is compiled into bytecode, which is then executed on the JVM. - JavaScript: - Type: JavaScript is a scripting language primarily used for web development. - Development: Developed by Netscape and first released in 1995. - Platform: JavaScript runs primarily in web browsers and executes directly in the browser. It is an integral part of HTML and CSS to create dynamic and interactive web pages. 2. Syntax and usage- Java: - Syntax: Java has strict, static typing and a complex syntax based on classes and objects. - Usage: Java is often used for server-side applications, desktop applications, mobile applications (via Android), and large enterprise systems. - JavaScript: - Syntax: JavaScript has flexible, dynamic typing and a rather loose syntax based on functions and prototypes. - Usage: JavaScript is mainly used for client-side web development to make websites interactive. It can also be used server-side with Node.js. 3. Compilation and execution- Java: - Compilation: Java code is compiled into bytecode before execution. - Execution: The bytecode is interpreted by the Java Virtual Machine (JVM) or compiled just-in-time to be executed on the target platform. - JavaScript: - Compilation: JavaScript code is interpreted at runtime, without a separate compilation phase. - Execution: JavaScript is interpreted and executed directly by web browsers, making it ideal for creating dynamic web pages. 4. Typing- Java: - Typing: Static and strongly typed. This means that variables and their types are checked at compile time. - JavaScript: - Typing: Dynamic and weakly typed. Variables can assume different types at runtime. Summary: - **Java** is a powerful, object-oriented programming language that runs on various platforms through the JVM. It is widely used for server-side and larger applications. - **JavaScript** is a dynamic scripting language used primarily for developing web pages and runs directly in the browser. It enables interactive features on web pages and can also be used server-side. FAQ 15: Updated on: 27 July 2024 18:12 |
