Hello,

There is no built-in way to convert javascript code to blocks. The reasons for this are:

1) Blockly doesn't support all javascript features. Eg anonymous functions, destructuring, etc.

2) Custom blocks may have arbitrary shapes and generate arbitrary code, which makes it hard to go from code -> blocks automatically :/

However! If you have a custom constrained version of javascript that you want to support (eg no anonymous functions, etc) it /should/ be possible to build something that converts from a string of javascript code to blocks =) But it would still be pretty tricky! You'll have to tokenize the string somehow, and create a way to map from those tokens to your blocks, and create a way to make sure they connect correctly. If you can get that working you should be golden.

I hope that helps! If you have any further questions please reply!

Hasti,

  This is probably not what you really want but I'll just point out there there have been applications using technologies other than Blockly that do the sort of thing that you're talking about.  One of them is the Droplet Editor (website, source) developed largely by Anthony and David Bau a few years ago.  It supports an older version of JavaScript, however.
