Cloudflare, Mozilla, and Facebook are developing BinaryAST to speed up JavaScript loading

Posted on

Engineers from Cloudflare, Mozilla, Facebook, and Bloomberg have proposed a new format called BinaryAST to accelerate the delivery and processing of JavaScript code when websites are opened in a browser. BinaryAST offloads the parsing phase to the server side and delivers a pre-compiled abstract syntax tree (AST).
