Hi All I just wanted to ask you all is it possible to make a javascript emulator or javascript emulators in general and in private and is it hard to do in general and in private? thanks for listening and your time and patience!

Dax · March 9th, 2009

Why not just run the javascript in a web browser? Or am I missing something here?

Yes, making emulators in javascript is possible.

A bit counter-intuitive though, as javascript cant execute native machine code or translate it (Java on the other hand could), thus why the platforms emulated are generally primitive old ones.

Heres an MSX emulator written in javascript (jMSX):

Amiga in javascript

ZX spectrum in javascript (JSSpeccy):

Very interesting actually, not something I would have really thought of as being possible. You learn something new everyday, I suppose.

There is one. Nescafe, for the NES.

Nescafe is in Java, not Javascript (I mentioned so in 'random thoughts'). Many emulators are coded in Java, but very rare are those made in javascript.

edit: adding 3 chip8 emulators coded in Javascript

Java is a fully fledged programming language, while javascript is destined for web pages (it could be similar to comparing tricycles and space shuttles).

Oh, ok, so a smaller version of java, to use in webpages, right?

Java is an API (Virtual Machine)
Javascript is a Language.

Nope, they're unrelated.

Quote:

JavaScript, despite the name, is essentially unrelated to the Java programming language, although both have the common C syntax, and JavaScript copies many Java names and naming conventions. The language's name is the result of a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun's Java runtime with their then-dominant browser. The key design principles within JavaScript are inherited from the Self and Scheme programming languages.
