# JavaScriptKit
[](https://github.com/swiftwasm/JavaScriptKit/actions/workflows/test.yml)
[](https://swiftpackageindex.com/swiftwasm/JavaScriptKit/documentation)
Swift framework to interact with JavaScript through WebAssembly.
## Quick Start
Check out the [Hello World](https://swiftpackageindex.com/swiftwasm/JavaScriptKit/tutorials/javascriptkit/hello-world) tutorial for a step-by-step guide to getting started.
## Overview
JavaScriptKit provides a seamless way to interact with JavaScript from Swift code when compiled to WebAssembly. It allows Swift developers to:
- Access JavaScript objects and functions
- Create closures that can be called from JavaScript
- Convert between Swift and JavaScript data types
- Use JavaScript promises with Swift's `async/await`
- Work with multi-threading
```swift
import JavaScriptKit
// Access global JavaScript objects
let document = JSObject.global.document
// Create and manipulate DOM elements
var div = document.createElement("div")
div.innerText = "Hello from Swift!"
_ = document.body.appendChild(div)
// Handle events with Swift closures
var button = document.createElement("button")
button.innerText = "Click me"
button.onclick = .object(JSClosure { _ in
JSObject.global.alert!("Button clicked!")
return .undefined
})
_ = document.body.appendChild(button)
```
