⚡🍹 Watt

A lightweight, expressive scripting language powered by VoltVM

🤔 About

Watt is a dynamically typed scripting language that combines functional and object-oriented programming paradigms. ⚡ It is designed to be expressive, flexible, and easy to use for scripting and application development.

✨ Features

• 🔄 Dynamically typed
• 🧠 FP + OOP
• 🪶 Clean syntax
• ⚙️ Compiled to bytecode (VoltVM)
• 🔍 Built-in reflection support
• 😋 Easy to learn

🚀 New

Watt is compiled to its own virtual machine, VoltVM. Volt VM brings:

• Great flexibility 🧩
• Good performance 🐇
• Nice reflection 🪞

💡 Examples

A few simple programs to show the expressive power of Watt.

✨ Watt files use the .wt extension.

    fun cook() {
        io.println('🥧 Cooking pie...')
        io.println('⚡ Pie cooked! Weight: '
                    + convert.to_string(weight)
        )
    }
