...The interpreter compiles BASIC source code into JavaScript at load time, enabling efficient execution within modern web environments without requiring external emulators or plugins. It supports traditional BASIC constructs such as loops, conditionals, and I/O operations, along with 24-bit color graphics functions (PSET, LINE, CIRCLE) and input handling (INKEY$, GETMOUSE). wwwBASIC brings retro programming into the modern web era, making it ideal for educational purposes, historical software preservation, and interactive demonstrations

...It offers map/filter/reduce, deep-cloning, templating, object traversal, function binding, and more, which makes it easier to write concise, expressive code rather than verbose loops and conditional logic. Many other libraries and frameworks (including Backbone) historically depended on or partnered with Underscore for their utility functions. Even though ES6+ and Lodash have overshadowed some of its role, Underscore remains influential and educational for how to design utility APIs.

...Its core reactivity system tracks changes to component state and efficiently updates only the affected parts of the DOM, which improves performance for both small widgets and larger applications. The library also offers powerful template syntax and lifecycle hooks so you can manage state, effects, loops, and events in a clear and expressive way while keeping your code close to native JavaScript.

Immutable JS data structures which are backwards-compatible with normal Arrays and Objects. Use them in for loops, pass them to functions expecting vanilla JavaScript data structures, etc. Whenever you deeply clone large nested objects, it should typically go much faster with Immutable data structures. This is because the library reuses the existing nested objects rather than instantiating new ones. In the development build, objects are frozen.

Monkberry is a highly optimized JavaScript library for building web user interfaces, designed to be extremely small, fast, and simple to use. It uses a template-based approach where UI components are written in a custom templating syntax that compiles directly into efficient JavaScript code. Unlike frameworks that rely on a virtual DOM, Monkberry updates only the necessary parts of the actual DOM, resulting in significantly improved performance. Its compiled templates leverage JavaScript...

...The idea is to avoid introducing a separate DSL for templating and instead use familiar JavaScript logic inside template tags to generate dynamic content. You write templates using <% %> scriptlet tags, <%= %> for output, and you can include other templates, pass data, and control flow with loops and conditionals. It’s fast because it compiles templates to JavaScript functions and caches them by default, so subsequent rendering is efficient. EJS supports both server-side render (in Node/Express) and client-side use in the browser, making it versatile for universal apps. Because you’re using raw JS, debugging is simple—the errors are standard JS stack traces with template line numbers included. ...
