An Absolute Beginner's Guide to Node.js

Technically speaking, HTML 5 introduced web-workers which allows javascript to have multiple threads (see 1). However, it's still useful to think about them as being single threaded since workers are sandboxed, meaning they don't have access to the global namespace. This avoids issues commonly found in concurrent programming. E.g., separate threads cannot read and write to the same variable since they don't have access to each other's namespaces.

While that's true, I don't believe it's applicable to node.js, so it's a bit out of scope for this article.

People coming from multi-threaded server environments should be aware that multi-threading does in fact exist in Node (scope of parent comment), but it's rather different from other more common concurrent event handling schemes. I.e., you cannot have shared mutable variables across threads (scope of article and ongoing async discussion). For examples, see https://npmjs.org/package/webworker-threads and https://github.com/cramforce/node-worker.

Fascinating. I didn't know that webworkers were available in node.js. I stand corrected, then.
