Hi

Is the syntax for JavaScript the same for Java?

No, they are different languages. (Though some of the
code and method names can look similar).

(moments later..)
Actually, now that I check the definition of 'syntax',
I'll need to ease back from the first answer.

The syntax of Java and JavaScript has a lot of
similarities, but probably no more than the similarities
common to any two randonly chosen, high level,
OO languages.

There's this site called "Google"....
Searching for "java versus javascript" is probably a good idea.

Yes, I use a thing called "Google" regularly

No.
They have a lot of similarities, probably because they both
took the basic syntax from the C language (or from another
language that took it from C).

Java and JavaScript has less in common that Java and C++
(or Java and C#, or C# and C++, or ...), mainly because
JavaScript is not a class based language like the other.

For the basic flow control statements (if, for, while, do),
which have nothing to do with being class-based or not,
the languages are much closer. If you can read one, you can
probably read another.

There are some aspects of JavaScript that were taken from Java, such as
putting the standard mathematical functions into a name space called
Math (though in the case of Java, the name space is in the form of a
class, and in the case of JavaScript, it is in the form of an object).

Hi
Greg

Most of the syntax for JavaScript is same as Java. There are many
differences
Like:-
In JavaScript we compare two strings for equality with ==
whereas,
In Java we compare two strings with equals() function.

They are different. One example of a difference: "class" is a reserved
word in Java, but not in JavaScript.

Moments after posting this, I find out that "class" is a "future
reserved word" in JavaScript, for the purpose of possible extensions. So
I'll rephrase the difference as:

"public class Foo {}" (without the quotes) is a legal Java compilation unit,
but not a legal JavaScript compilation unit.
