Mocha works in the browser. Mocha releases will include new builds of./mocha.js/./mocha.csss that can be used in the browser. Mocha will be able to tell if it should wait for the function to be called by adding an argument (usually called done) to it() to a test-callback to make sure it is aware of this. This callback accepts either an Error instance or subclass thereof, and any other value is invalid usage. It throws an error, usually resulting in a failed test. These reporters expect Mocha's to know how many tests it will run before execution. This information is not available in parallel mode because test files are only loaded when they are being run. Serial mode will stream the results of tests as they occur. Parallel mode buffers reporter output; reporting will occur after each file has been completed. In practice, the reporter output will appear as "chunks", but will otherwise be identical. A test file that is slow may cause a significant pause.

Node.js is an asynchronous JavaScript runtime that drives JavaScript calls. It's designed to create scalable network applications. Node.js will go to sleep if there isn't any work being done. This is in contrast with the more common concurrency model today, where OS threads are used. Thread-based networking is slow and difficult to use. Node.js users are not at risk of deadlocking the process because there are no locks. Nearly every function in Node.js performs I/O. The process never blocks unless the I/O is performed using synchronous Node.js methods standard library. Scalable systems are easy to create in Node.js because nothing blocks. Node.js is inspired by and similar to Ruby's Event Machine, and Python's Twisted. Node.js extends the event model a little further. It presents an event loop instead of a library as a runtime construct.
