Neutron
Neutron is a lightweight, object-oriented toy programming language designed for learning and experimentation.
This VS Code extension provides full syntax highlighting, including keywords, variables, constants, strings, numbers, function definitions and calls, object method calls, and use imports.

var, if, class, fun, this, etc.) in bluish-grey
- Variables in light blue
- Constants (
true, false, null, ALL_CAPS) in deep blue
- Strings in orange/yellow
- Numbers in cyan/purple
- Function definitions (
fun greet()) in blue
- Function calls (
say(), counter.increment()) in bright yellow
- Object method calls only highlight the method, not the object
use imports: use keyword in blue, module names in green
- Supports object-oriented constructs
- Classes, methods,
this keyword, multiple instances
- Lightweight and easy to install

Known Issues
