Thread

Threads utility is used to implement multi-threading algorithms - creating and starting own threads, synchronize functions, wait and notify of lock objects.

Basic Usage

var threads = require("core/v4/threads");
var response = require("http/v4/response");

response.setContentType("text/plain; charset=UTF-8");

// Define a JavaScript function
function runnable() {
    response.println("Hello World from a Thread!");
};

// Pass a JavaScript function
var worker = threads.create(runnable, "I am a thread");
response.println(worker.getName());
worker.start();
worker.join(); // to be able to print to the response

response.flush();
response.close();
