你所谓的循环引用的对象,具体是个什么样子?常规的数组去重,我就array转set,在转回array。写起来简单,性能好不好不太清楚class Greeter {
greeting: string; constructor(message: string) { this.greeting = message;
}
greet() { return "Hello, " + this.greeting;
}
}const a = new Greeter('1');const b = new Greeter('2');const c = new Greeter('3');const myArr = [a, a, a, a, b, c, c, c, b, c, c, b, b, b, b, c, c, a, a, a, a];const mySet = new Set(myArr);const finalArr = Array.from(mySet);console.log(finalArr)
