Something Completely Parenthetical

And there it is. A Lisp compiler in a <script> tag. The parentheses compile to semicolons, the semicolons execute, and the page renders. It’s not madness. It’s just compilation.

“But it looks like madness.”

“Most good ideas do.”

The book’s title has been earned. And Now for Something Completely Parenthetical — s-expressions in the browser, compiling to JavaScript, running on the web platform. The most parenthetical thing the book describes, and the simplest piece of infrastructure in the compiler.
