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.
  • Full ES2020 Support
    QuickJS supports the full ES2020 specification, providing modern JavaScript features and syntax, which is advantageous for developers who want to use the latest JavaScript features.
  • 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.

  • Servo in 2024: stats, features and donations
    And some lightweight alternatives like Bellard's QuickJS (https://bellard.org/quickjs/) in C and Kiesel (https://kiesel.dev/) in Zig. - Source: Hacker News / 3 months ago
  • Building Static HTML Pages with JSX Server-Side Rendering
    Built on a highly optimized JavaScript runtime powered by QuickJS, Query offers fast startup times and efficient execution. Its built-in caching mechanism further enhances performance by storing function responses, reducing database load and latency. This focus on speed makes Query a standout choice for server-side rendering, especially in applications with many components. - Source: dev.to / 4 months ago
  • Lua Is So Underrated
    Which JS VMs have you tried embedding? People in this thread have suggested https://github.com/Moddable-OpenSource/moddable, and https://duktape.org/, but I haven't tried any of them. - Source: Hacker News / 4 months ago
  • Introducing our Next-Generation JavaScript SDK
    Where the previous SDK was built on top of the QuickJS JavaScript engine and the Javy runtime, the new SDK is built on top of the Firefox browser’s SpiderMonkey engine, and the Bytecode Alliance’s StarlingMonkey runtime and ComponentizeJS WIT bindings generator. - Source: dev.to / 5 months ago
