Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.
JavaScript is a scripting language that is used to create and control dynamic website content, i.e. things that move, refresh, or otherwise change on your screen without requiring you to manually reload a web page. JavaScript is also used in game development and mobile app development.
Example:
Java:
public class HelloWorld {
public static void main(String[] args) {
System.out.println(“Hello World!”);
}
}
JavaScript:
console.log(“Hello World!”);
