We have now moved the Web Assembly build into the `wasm` package, plus added a code of conduct for those contributing.
The parser has been even more modularized in this release making it easier to add new parsing rules.
Boa has migrated it's object implemention to FXHash which brings much improved results over the built-in Rust hashmaps (at the cost of less DOS Protection).
Tests have also been moved to their own files, we had a lot of tests in some modules so it was time to separate.
## New Parser
Most of the work in this release has been on rewriting the parser. A big task taken on by [HalidOdat](https://github.com/HalidOdat), [Razican](https://github.com/Razican) and [myself](https://github.com/jasonwilliams).
The majority of the old parser was 1 big function (called [`parse`](https://github.com/boa-dev/boa/blob/019033eff066e8c6ba9456139690eb214a0bf61d/boa/src/syntax/parser.rs#L353)) which had some pattern matching on each token coming in.
The easy branches could generate expressions (which were basically AST Nodes), the more involved branches would recursively call into the same function, until eventually you had an expression generated.
This only worked so far, eventually debugging parsing problems were difficult, also more bugs were being raised against the parser which couldn't be fixed.
We decided to break the parser into more of a state-machine. The initial decision for this was inspired by [Fedor Indutny](https://github.com/indutny) who did a talk at (the last) JSConf EU about how he broke up the old node-parser to make it more maintanable. He goes into more detail here https://www.youtube.com/watch?v=x3k_5Mi66sY&feature=youtu.be&t=530
The new parser has functions to match the states of parsing in the spec. For example https://tc39.es/ecma262/#prod-VariableDeclaration has a matching function `read_variable_declaration`. This not only makes it better to maintain but easier for new contributors to get involed, as following the parsing logic of the spec is easier than before.
Once finished some optimisations were added by [HalidOdat](https://github.com/HalidOdat) to use references to the tokens instead of cloning them each time we take them from the lexer.
This works because the tokens live just as long as the parser operations do, so we don't need to copy the tokens.
On top of that the lexer no longer panics on errors including Syntax Errors (thanks @adumbidiot), instead you get some output on where the error happened.
