Java and JavaScript are two different programming languages that share a similar name but have different features, syntax, and applications. Here are some key differences between Java and JavaScript:

Java

• Java is an object-oriented programming language that creates applications that run in a virtual machine or browser.
• Java is a compiled language, meaning that you write code, then run it through a compiler and create bytecode. The bytecode is then run in a Java Virtual Machine (JVM) .
• Java is statically typed, which means that data types are determined at compile time.
• Java is class-based, and constructors are special functions that can only be called at object creation.
• Java requires all non-block statements to end with a semicolon, and it uses block-based scoping.
• Java has an implicit this scope for non-static methods and implicit class scope.

JavaScript

• JavaScript is an object-oriented scripting language that is used to make web pages interactive.
• JavaScript is an interpreted language, meaning that it doesnt get compiled but is interpreted as the script runs.
• JavaScript is dynamically typed, which means that data types are determined at runtime.
• JavaScript is prototype-based, and "constructors" are just standard functions.
• JavaScript inserts semicolons at the ends of certain lines, and it uses function-based scoping.
• JavaScript has an implicit global scope.

While Java and JavaScript share some similarities, they are used for different purposes. Java is commonly used for creating desktop applications, mobile apps, and server-side applications, while JavaScript is used for creating interactive websites and web-based projects.
