  • Learning Curve
    Despite its user-friendly design, there can be a learning curve for new users to fully understand and utilize all the features.
  • Potential Over-reliance
    Developers might become overly reliant on automated code suggestions, which could impact their coding skills in the long term.
  • Variable Performance
    Performance may vary depending on the complexity of the codebase and the specific languages being used.
  • Integration Bugs
    Like any software, there could be occasional bugs or issues during integration with different development environments.

QuickJS features and specs

  • Lightweight
    QuickJS is designed to be lightweight with a small footprint, making it easy to embed in applications and suitable for resource-constrained environments.
  • Fast Startup Time
    QuickJS offers very fast startup times, which can be beneficial for applications that require quick script execution without a long initialization period.

  • Embeddability
    Being easy to integrate into other applications or systems, QuickJS provides a simple C API, which facilitates embedding it in various software and platforms.
  • Single File Distribution
    QuickJS can be distributed as a single file, simplifying packaging and distribution without needing external dependencies.
  • Memory Efficiency
    Its memory efficient design allows QuickJS to run scripts in environments with limited memory resources, making it suitable for IoT devices and embedded systems.

Possible disadvantages of QuickJS

  • Limited Ecosystem
    QuickJS, being a relatively new and niche project, has a smaller ecosystem compared to more established JavaScript engines like V8, which means fewer libraries and community resources are available.
  • Performance
    While QuickJS is efficient, it may not deliver the same high-performance execution as more mature engines like V8, especially in applications requiring intensive computational processing.
  • Lack of Long-term Support
    QuickJS may not have the same level of long-term support and ongoing development as larger projects maintained by large companies or communities.
  • Single-threaded
    QuickJS runs in a single thread, which can be a limitation for applications that require multithreading support for parallel processing.
  • Limited Debugging Tools
    Compared to more popular JavaScript engines, QuickJS has fewer debugging tools and integrations, which might make development and troubleshooting more challenging.

  • Vim 9.2 Released
    You don't need V8 for running JS for scripting, you have quickjs[1] or mquickjs[2] for example. You might have problems importing npm packages, but as we can see from lua plugins you don't even need support for package managers. Performance is not as good as luajit, but it is good enough [1]: https://bellard.org/quickjs/ [2]: https://github.com/bellard/mquickjs. - Source: Hacker News / 5 months ago

  • Building a JavaScript Runtime from Scratch using C
    For those who would like a true "from scratch" implementation of JavaScript, Fabrice Bellard's QuickJS [1] is clean, readable and approachable. It's a full implementation of modern JavaScript in a straightforward project, not nearly as complex or difficult as V8. [1] https://bellard.org/quickjs/. - Source: Hacker News / 10 months ago
  • The many, many, many JavaScript runtimes of the last decade
    I see a few mentions of QuickJS, but they all refer to the fork of Bellard's QuickJS https://bellard.org/quickjs/, which I think deserves a mention. It seems to be still active (last release 2025-04-26, GitHub mirror at https://github.com/bellard/quickjs shows some activity). - Source: Hacker News / 12 months ago
  • SQLite JavaScript: Extend your database with JavaScript
    This is a fantastic approach. BTW, it looks like the js engine is "QuickJS" [0]. (I'm not familiar with it myself.) I like it because sqlite by itself lacks a host language. (e.g., Oracle's plsql, Postgreses pgplsql, Sqlserver's t-sql, etc). That is: code that runs on compute that is local to your storage. That's a nice flexible design -- you can choose whatever language you want. But quite typically you... - Source: Hacker News / about 1 year ago
