帮我使用ts的泛型定义一个动画类的代码

好的，以下是使用 TypeScript 泛型定义的动画类代码：

interface AnimationOptions {
  duration: number;
  easing: string;
}

class Animation<T> {
  private startValue: T;
  private endValue: T;
  private duration: number;
  private easing: string;

  constructor(startValue: T, endValue: T, options: AnimationOptions) {
    this.startValue = startValue;
    this.endValue = endValue;
    this.duration = options.duration;
    this.easing = options.easing;
  }

  animate(onUpdate: (value: T) => void, onComplete?: () => void) {
    const startTime = Date.now();
    const endTime = startTime + this.duration;

    const animateFrame = () => {
      const now = Date.now();
      const progress = Math.min(1, (now - startTime) / this.duration);
      const easedProgress = this.easingFunction(progress);

      const currentValue = this.interpolate(this.startValue, this.endValue, easedProgress);
      onUpdate(currentValue);

      if (now < endTime) {
        requestAnimationFrame(animateFrame);
      } else if (onComplete) {
        onComplete();
      }
    };

    requestAnimationFrame(animateFrame);
  }

  private easingFunction(progress: number) {
    // TODO: Implement easing function
    return progress;
  }

  private interpolate(startValue: T, endValue: T, progress: number) {
    // TODO: Implement interpolation function
    return startValue;
  }
}

希望这个代码对你有帮助！
