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.

ACE (Ajax Code Editor) features and specs

  • Rich Feature Set
    ACE provides syntax highlighting, line numbers, code folding, autocompletion, and more, making it quite powerful for web-based coding.
  • Customizability
    Users can extend and customize ACE by adding themes, changing the key bindings, and altering other settings to fit their workflow.
  • Wide Language Support
    ACE supports syntax highlighting for numerous programming languages, enabling developers to work with varied code bases within the same editor.
  • In-Browser Operation
    Being a web-based code editor, ACE can be used directly in the browser without any need for installation or configuration, providing immediate access across devices.
  • Open Source
    As an open-source project, ACE allows developers to contribute to the codebase, ensure transparency, and avoid vendor lock-in.

Possible disadvantages of ACE (Ajax Code Editor)

  • Performance Limitations
    Being a JavaScript-based editor running in the browser, ACE may experience performance issues when handling particularly large files compared to native desktop editors.
  • Lack of Advanced IDE Features
    ACE is mainly a code editor and does not provide some of the advanced features found in full-fledged IDEs, such as built-in debugging tools or integrated terminal support.
  • Limited Offline Use
    Since ACE is designed for web-based environments, there might be limitations or additional steps required to use it effectively offline.
  • Dependency on Browser
    The performance and capability of ACE can vary depending on the browser being used, making it subject to each browser's limitations and quirks.
  • Learning Curve
    Setting up custom configurations and understanding the full range of features may require a learning period, especially for users new to web-based editors.

    I used a note system built on top of Fossil as my primary system for quite a while. Here are the details in case anyone is interested. Fossil allows CGI extensions[1]. There's a database for tickets, but that's just a regular SQLite table that you can use to store anything you want, and it's version controlled and queryable. I stored the notes plus metadata in the tickets database. The CGI returned HTML with the... - Source: Hacker News / over 1 year ago
  • Writing a (simple) code editor for the web?
    Hey there! Thanks for reaching out. Writing a code editor with syntax highlighting in a browser can be a little tricky, but it's definitely doable.
