Vapor.js is making fun of the trend of JavaScript frameworks. Most of the existing frameworks advertise their file size, since a small size is desirable for fast page loads. Vapor.js is an empty file.
Recently the authors of a popular JavaScript/CSS framework, Bootstrap, decided to remove the semicolons from their JavaScript (since they're technically optional).
Douglas Crockford is the author of a tool called JSMin that compresses JavaScript files. He is known ot have strong opinions on JavaScript coding style, as is evident in his book JavaScript: The Good Parts and his JavaScript formatting/checking tool, JSLint.
Someone pointed out that now that Bootstrap no longer has semicolons it no longer under JSMin. Douglas Crockford was pulled into the conversation, where he expressed his strong opinions on the use of semicolons in JavaScript
Semicolon.js is making fun of all of this by adding a semicolon to Vapor.js.
(Oh, darn. The person I was replying to deleted their post. Anyway, they said something along the lines of: "I know this is a joke, but I don't get it. Am I missing some subtle commentary?")
