# Zignal

#### 介绍  
简单的signal实现  
*A simple signal implementation*

```js
import { zignal, computed } from './zignal.js';

// 创建普通信号  
// Create a regular signal
const count = zignal(0);

// 创建计算信号  
// Create a computed signal
const doubleCount = computed(() => count.get() * 2, [count]);

// 订阅普通信号  
// Subscribe to the regular signal
const unsubscribeCount = count.subscribe((newValue) => {
  console.log(`count 变更为 ${newValue}`);
  // Output: count changed to ${newValue}
});

// 订阅计算信号  
// Subscribe to the computed signal
const unsubscribeDouble = doubleCount.subscribe((newValue) => {
  console.log(`doubleCount 变更为 ${newValue}`);
  // Output: doubleCount changed to ${newValue}
});

// 更新普通信号  
// Update the regular signal
count.set(1);
// 输出 count 变更为 1, doubleCount 变更为 2
// Logs: count changed to 1, doubleCount changed to 2

// 取消订阅  
// Unsubscribe
unsubscribeCount();
unsubscribeDouble();

// 销毁计算信号  
// Dispose of the computed signal
doubleCount.dispose();
```
