  • Performance goal

    It is important for Nova to be able to show memory savings from its novel heap layout, but performance must also be shown to be reasonable lest the entire project be regarded a gimmick.

  • Struct-of-Arrays vector type

    Nova and the JS parser library we use, oxc, both have a vested interest in improving the state of Struct-of-Arrays vector libraries available in the Rust ecosystem. We have already decided to join forces and create a library that will work for both of us. The benefit of a SoA vector is that it enables vastly improved cache locality for stored "structural" data, especially when iterating over parts of the data. (Downsides are f.ex. higher growth costs.)

  • Technical maintenance

    Nova is young and the code base is generally well under control, but some warts have seeped in during the nearly two years of active development.

    •1/2 issues closed
    50% complete1 open1 closed

  • Missing builtin method

    Nova is still missing some builtin methods from the specification, some more commonly used than others.

    Due by October 3, 2025
    •0/5 issues closed
    0% complete5 open0 closed

  • Missing specification features

    Nova passes more than 50% of the Test262 conformance suite, but a bunch of important language specification level features are still missing before the engine can be considered mature.

    Due by October 3, 2025
    •6/10 issues closed
    60% complete4 open6 closed

  • Finishing AsyncGenerators

    Asynchronous generators are a rare but important breed of JavaScript functions; they form the basis of various convenient streams and other related features. We are still missing some parts of the specification on this end

    Due by October 3, 2025
    •2/2 issues closed
    100% complete0 open2 closed

  • ECMAScript modules

    Modern JavaScript is nothing without the module system. Implementing it is a necessity

    Due by October 3, 2025
    •4/4 issues closed
    100% complete0 open4 closed

  • Interleaved garbage collection

    A JavaScript engine that cannot stop JavaScript execution to perform garbage collection is mostly a toy. Nova's GC is currently only interleaved behind a flag and this needs to change.

    Due by October 3, 2025
    •5/6 issues closed
    83% complete1 open5 closed

  • BuiltinFunction implementations

    Fully implement the BuiltinFunction stubs
