Answer 1

Here are some differences between the two languages:

Java is a statically typed language; JavaScript is dynamic.
Java is class-based; JavaScript is prototype-based.
Java constructors are special functions that can only be called at object creation; JavaScript "constructors" are just standard functions.
Java requires all non-block statements to end with a semicolon; JavaScript inserts semicolons at the ends of certain lines.
Java uses block-based scoping; JavaScript uses function-based scoping.
Java has an implicit this scope for non-static methods, and implicit class scope; JavaScript has implicit global scope.
Here are some features that I think are particular strengths of JavaScript:

JavaScript supports closures; Java can simulate sort-of "closures" using anonymous classes. (Real closures may be supported in a future version of Java.)
All JavaScript functions are variadic; Java functions are only variadic if explicitly marked.
JavaScript prototypes can be redefined at runtime, and has immediate effect for all referring objects. Java classes cannot be redefined in a way that affects any existing object instances.
JavaScript allows methods in an object to be redefined independently of its prototype (think eigenclasses in Ruby, but on steroids); methods in a Java object are tied to its class, and cannot be redefined at runtime.

Answer 6

How is JavaScript different from Java?

The JavaScript programming language, developed by Netscape, Inc., is not part of the Java platform.

JavaScript does not create applets or stand-alone applications. In its most common form, JavaScript resides inside HTML documents, and can provide levels of interactivity to web pages that are not achievable with simple HTML.

Key differences between Java and JavaScript:

Java is an OOP programming language while Java Script is an OOP scripting language.

Java creates applications that run in a virtual machine or browser while JavaScript code is run on a browser only.

Java code needs to be compiled while JavaScript code are all in text.

They require different plug-ins.
