🚀 性能测试

Eventure vs EventEmitter3 vs EventEmitter2 vs mitt (每次测轮跑 ×10⁵ 次) 该测试可复现，请查看 tinybench，考虑到小于 5% 的误差在实际应用中完全可以忽略， 我们并不想夸大性能优势，Eventure 的目的是保证功能正确的同时保持第一梯队的性能，EE3 缺乏功能，EE2 混乱且难维护，这便是 Eventure 存在的意义。

🧪 示例用法

import { Eventure } from "eventure"

interface MyEvents {
  foo: [string];                         // 等价于 (arg1: string) => void
  bar: [number, number];                // (arg1: number, arg2: number) => void
  test: (a: number, b: number) => number
  numEvent: (value: number, next: (value: number) => number) => number;
}

const emitter = new Eventure<MyEvents>()

emitter.on("foo", (message) => {
  console.log(message)
})

emitter.emit("foo", "你好，世界")
