What is the Difference Between Java and JavaScript?
🆚 Go to Comparative Table 🆚Java and JavaScript are two distinct programming languages with different features and use cases. Here are some key differences between them:
- Nature of the language: Java is an object-oriented, class-based, all-purpose programming language, while JavaScript is an object-oriented, cross-platform scripting language used for creating interactive web content.
- Typing: Java is statically typed, meaning that data types are determined at compile time, while JavaScript is dynamically typed, meaning that data types are determined at runtime.
- Compiler vs. Interpreter: Java is a compiled language, meaning that you write code, then run it through a compiler to create bytecode, which is then run in a Java Virtual Machine (JVM). In contrast, JavaScript is an interpreted language, meaning that it doesn't get compiled but is interpreted as the script runs.
- Platform: Java is used for app development, smart devices, and backend applications, while JavaScript is primarily used for web development, both on the frontend and backend.
- Scope: Java uses block-based scoping, while JavaScript uses function-based scoping.
- Constructors: In Java, constructors are special functions that can only be called at object creation, while in JavaScript, "constructors" are just standard functions.
- Semicolons: Java requires all non-block statements to end with a semicolon, while JavaScript inserts semicolons at the ends of certain lines.
In summary, Java and JavaScript have different characteristics, uses, and syntax. Java is more widely used for app development and backend applications, while JavaScript is primarily used for web development and creating interactive web content.

Comparative Table: Java vs JavaScript
Here is a table highlighting the differences between Java and JavaScript:
Feature | Java | JavaScript |
---|---|---|
Compilation | Compiled language, requires a compiler to create bytecode | Interpreted language, no compilation required |
Execution | Bytecode runs in a Java Virtual Machine (JVM) | Script runs in web browser or Node.js runtime |
Syntax | Similar to C and C++, full OOP language | Basic syntax similar to Java and C++ |
Objects | Class-based objects | Prototype-based objects |
Type Checking | Strongly typed, variable checks at compile-time | Weakly typed, variable checks at runtime |
File Extension | .java |
.js |
Usage | Primarily used for client and server-side applications | Used for client-side web application behavior and interactivity |
Accessibility | Complete functionality available after compilation | Limited features and commands available |
Learning Curve | Steeper learning curve due to OOP concepts and compile-time checking | Easier learning curve with dynamic capabilities |
Note that while Java and JavaScript share some similarities in syntax, they are fundamentally different languages with distinct features and use cases.
