ArachnoScript Runtime v0.2.1 Released 🚀 - Major Improvements & New Features

Hey Dev.to!

It's been an exciting journey since I first introduced ArachnoScript. Today, I'm happy to announce the release of ArachnoScript Runtime v0.2.1.

This version brings a lot of under-the-hood improvements, bug fixes, and exciting new features.

What's New in v0.2.1

Improved For Loop Syntax

// Old syntax
for (i = 0; i < 10; i++) {}

// New syntax
for (spawn i = 0; i < 10; i++) {}

Improved CLI

Bash

# Old way
are ./path/to/script.as

# New way
are run ./path/to/script.as

Quick evaluation

are -e "Console.log('Hello World!');"

Major Changes

Optimized lexer + fixed string lexing bugs
Many parser fixes and improvements (constructor logic, object literals, if statements, class properties, etc.)
Significant Runtime improvements
New macros: #_http_listen, #_http_serve, #_real_path, #_path_relative_to_file, etc.
Removed old #_http_listen_and_serve macro
Added new http and regexp standard library modules
Updated many existing standard library modules (strings, arrays, io, fs, math, etc.)
Fixed several bugs (including await, macros, and path handling)
Many stability and performance improvements

How to Install (Windows)

Go to the GitHub repository: https://github.com/ECMA-King87/ArachnoScript-Runtime-Engine-ARE-
Go to the Releases section
Download the latest v0.2.1 assets
Run the installer (or extract the zip)
Start using the are command

Note: Currently focused on Windows. macOS and Linux support will arrive by the v1.0 release.

Hi Dev.to 👋

I want to share a personal project I’ve been working on called ArachnoScript (AS) — a programming language inspired by JavaScript, but designed from scratch with different trade-offs and semantics.

JavaScript is my favourite language, but while learning it deeply, I started asking questions like:

What if function parameters weren’t passed by reference?

What if arrays weren’t objects?

What if constructors, instances, and objects were distinct runtime types?

That curiosity turned into ArachnoScript.

What makes AS different?

Deep-copied function parameters (no accidental mutation)

(Later on: Explicit sharing of references by value)

Explicit runtime types: object, array, class, instance, macro, raw

JS-like syntax without being JS

Custom runtime (ARE) written in Go

Built-in server + web APIs

Experimental UI framework (Verdex) using ASX (JSX-like syntax)

Trying it out

You don’t need to build anything yourself — I provide prebuilt binaries for:

Linux

macOS

Windows

Docs, examples, and downloads are all here:
👉 https://github.com/ECMA-King87/ArachnoScript-Programming-Language.git

The runtime source is private for now, but everything needed to use the language is public.

Why I built this

This project is mainly about learning, experimenting, and understanding language design at a deeper level — not competing with existing languages.

If you’re interested in programming languages, interpreters, or just trying something new, I’d love your feedback.
