Noop (/ˈnoʊ.ɒp/, like no-op) was a project by Google engineers Alex Eagle and Christian Gruber aiming to develop a new programming language. Noop attempted to blend the best features of "old" and "new" languages, while syntactically encouraging well accepted programming best-practices. Noop was initially targeted to run on the Java Virtual Machine.^[1]

Noop progressed past its initial proposals into a limited interpreter, but according to the project owners they no longer intend to pursue the language any further.^[2] Among the reasons cited for discontinuing work on the language was the initial release of Kotlin, which achieves many of the language goals of Noop.^[3] The Noop language can be executed as an interpreted language, as a compiled language, or as Java code.^[4]

The Noop language was created by Google. It was presented during the 2009 edition of the JVM Language Summit held in Santa Clara, California from September 16 to 18, 2009.^[5]

Hello world in Noop

import noop.Application;
import noop.Console;

class HelloWorld(Console console) implements Application {

  Int main(List args) {
    String s = "Hello World!";

    console.println(s);
    return 0;
  }
}
