JavaScript, referred to as "JS", is a lightweight, interpreted or just-in-time compiled programming language with function priority. Although it is famous as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is a dynamic scripting language based on prototype programming and multi-paradigm, and supports object-oriented, imperative, and declarative paradigms. .
JavaScript ("JS" for short) is a lightweight, interpreted or just-in-time compiled programming language with function priority. Although it is famous as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is a dynamic scripting language based on prototype programming, multi-paradigm, and supports object-oriented, imperative, and declarative ( such as functional programming) paradigm.
JavaScript is an interpreted language, that is to say, it does not need to be compiled in advance, but is interpreted and executed line by line by the interpreter at runtime. JavaScript is a weakly typed or dynamically typed language, which means that you do not need to declare the type of a variable in advance. The type of the variable is determined when you first assign a value to it, and can be changed later.
JavaScript was originally designed to add interactivity to HTML (an application under Standard Universal Markup Language) pages. However, it is also used in many non-browser environments. JavaScript is based on prototype programming, a multi-paradigm dynamic scripting language, and supports object-oriented, imperative, and declarative (such as functional programming) paradigms.
Overall, JavaScript is a powerful and flexible programming language that is widely used in web development and many other fields.

How does the JVM contribute to Java's 'write once, run anywhere' (WORA) capability?May 02, 2025 am 12:25 AMJVM implements the WORA features of Java through bytecode interpretation, platform-independent APIs and dynamic class loading: 1. Bytecode is interpreted as machine code to ensure cross-platform operation; 2. Standard API abstract operating system differences; 3. Classes are loaded dynamically at runtime to ensure consistency.
How do newer versions of Java address platform-specific issues?May 02, 2025 am 12:18 AMThe latest version of Java effectively solves platform-specific problems through JVM optimization, standard library improvements and third-party library support. 1) JVM optimization, such as Java11's ZGC improves garbage collection performance. 2) Standard library improvements, such as Java9's module system reducing platform-related problems. 3) Third-party libraries provide platform-optimized versions, such as OpenCV.
Explain the process of bytecode verification performed by the JVM.May 02, 2025 am 12:18 AMThe JVM's bytecode verification process includes four key steps: 1) Check whether the class file format complies with the specifications, 2) Verify the validity and correctness of the bytecode instructions, 3) Perform data flow analysis to ensure type safety, and 4) Balancing the thoroughness and performance of verification. Through these steps, the JVM ensures that only secure, correct bytecode is executed, thereby protecting the integrity and security of the program.

How has Java's platform independence evolved over time?May 02, 2025 am 12:12 AMJava's platform independence is continuously enhanced through technologies such as JVM, JIT compilation, standardization, generics, lambda expressions and ProjectPanama. Since the 1990s, Java has evolved from basic JVM to high-performance modern JVM, ensuring consistency and efficiency of code across different platforms.
What are some strategies for mitigating platform-specific issues in Java applications?May 01, 2025 am 12:20 AMHow does Java alleviate platform-specific problems? Java implements platform-independent through JVM and standard libraries. 1) Use bytecode and JVM to abstract the operating system differences; 2) The standard library provides cross-platform APIs, such as Paths class processing file paths, and Charset class processing character encoding; 3) Use configuration files and multi-platform testing in actual projects for optimization and debugging.

How does GraalVM relate to Java's platform independence goals?May 01, 2025 am 12:14 AMGraalVM enhances Java's platform independence in three ways: 1. Cross-language interoperability, allowing Java to seamlessly interoperate with other languages; 2. Independent runtime environment, compile Java programs into local executable files through GraalVMNativeImage; 3. Performance optimization, Graal compiler generates efficient machine code to improve the performance and consistency of Java programs.
