JSConsole

This is a JavaScript console powered by its own JavaScript interpreter, written in JavaScript.

It is very experimental and a work in progress.

Features

• Autocomplete
• Eager evaluation
• Displaying object metadata
• Top-level await
• Non-isolated execution (transparently works within the browser context, so you can use the DOM and browser APIs)
• Preview window
• Console log can be shared via a link
• Supports TypeScript (strips erasable types without type checking)

Interpreter

The console is powered by its own JavaScript interpreter. It is non-sandboxed by design.

The rationale consists of two parts:

• To have a console that transparently works within the current browser realm, so we can play with the DOM and browser APIs – the same way we use native DevTools browser consoles
• To provide the best possible UX/DX that closely mirrors native DevTools browser consoles' capabilities, such as autocomplete, eager evaluation, and displaying object metadata
