Just have found some funny behavior of the Visual Studio 2008 editor.  Sorry if it is already well known bug.

If you happened to have a JavaScript function named “assert” in your code (and there is pretty high likelihood in my opinion), for example something like:

function assert(x, message) {
    if (x) console.log(message);
}

then when either Format Document (Ctrl + K, Ctrl + D) or Format Selection (Ctrl + K, Ctrl + F) command is applied to the document/block containing the function, the result of the formatting will be:

functionassert(x, message) {
    if (x) console.log(message);
}

That’s it. function and assert are now joined into one solid word.

So be aware of the fact in case you suddenly start receiving  strange exception in your JavaScript code: missing ; before statement functionassert(x, message)

And no, it is not an April Fool's joke. Just try for yourself.
