how can we differentiate JavaScript in java?

Answer 1

There are big differences.

Java is a language that is compiled.

JavaScript is a runtime language.

Java uses classes for everything.

Hello world in both languages:

JavaScript:
alert("Hello World!");
or
document.write("Hello World!");

Java:

public static void main {
system.out.printIn("Hello World!");
}

In Java (Same with CSharp) you need to use Main to print Hello World. Java is an Object Oriented Language, and JavaScript is a functional language (I think).

And... JavaScript is used in the browser. (JavaScript can be used with Unity, but when used with it it's usually called "UnityScript"
) Java is used in the computer itself.
