  1. GOTOs in JavaScript are now possible

    And I'm back with my crazy experiments. Currently I'm actively playing with Ragel - state machine compiler that generates highly optimized code for streaming lexers, scanners etc. in a set of languages (C, Java, Ruby, C#, ...). Unfortunately, it didn't have support for JavaScript, and I recently implemented it (likely to…

  2. ES6 modules are dead, long live C preprocessor!

    Did you know you could use C preprocessor even for JavaScript files? (yes, it doesn't care about syntax that much) Say, we want to implement C-like "modules" (inclusions) in JavaScript. Create first file 1.js (filenames don't matter) like this: #ifndef HELLO_1 #define HELLO_1 console.log('hello'); #endif…

  3. Started work on ES6 -> asm.js conversion

    View on GitHub I know this sounds crazy, but I always wondered why do we always give out such a speedup technique as asm.js (it speeds up code in all the modern browsers!) to developers from other languages if we can use it for own code in JavaScript as…

  4. [Potentially ES7] function bind syntax in Babel

    View original post Babel 5.4 was just released and with it comes support for a new experimental ES7 syntax proposed by Kevin Smith (@zenparsing) and implemented in Babel by Ingvar Stepanyan (@RReverser). Warning: This syntax is highly experimental and you should not use it for anything serious (yet). If…

  5. A few more words on Acorn-JSX

    Initially this was part of my email response to Lou Husson after mentioning Acorn-JSX in Facebook React Community Round-up #20 and reaching me out, but decided that someone else might find it useful too. UPD (June 12, 2015): Facebook deprecates own parsing and transformation tools in favor of Acorn, Acorn-JSX…

  6. Alternative, faster React.js JSX parser

    View on GitHub This is modification of Acorn - a tiny, fast JavaScript parser, written completely in JavaScript. UPD (June 12, 2015): Facebook deprecates own parsing and transformation tools in favor of Acorn, Acorn-JSX and Babel. Looks like I'll need to be more careful about updates starting from now 😜 It…
