## What is Splash?

Splash is Makepad's dynamic scripting language designed for:
- AI-assisted workflows
- Dynamic UI generation
- Rapid prototyping
- HTTP requests and async operations

## Script Macro

```rust
// Embed Splash code in Rust
script!{
    fn main() {
        let x = 10;
        console.log("Hello from Splash!");
    }
}
```

## Execution

```rust
// Evaluate Splash code at runtime
cx.eval(code_string);

// With context
cx.eval_with_context(code, context);
```

## Basic Syntax

### Variables

```splash
let x = 10;
let name = "Makepad";
let items = [1, 2, 3];
let config = { width: 100, height: 50 };
```

### Functions

```splash
fn add(a, b) {
    return a + b;
}

fn greet(name) {
    console.log("Hello, " + name);
}
```

### Control Flow

```splash
// If-else
if x > 10 {
    console.log("big");
} else {
    console.log("small");
}

// Loops
for i in 0..10 {
    console.log(i);
}

while condition {
    // ...
}
```

## Built-in Objects

### console

```splash
console.log("Message");
console.warn("Warning");
console.error("Error");
```

### http

```splash
// GET request
let r
