const performanceInfro = reactive navigationStart 0 domEnd 0 domready 0 onload 0 memory 0帮我定义一个ts的接口以及加上一个默认值但是可以被修改

interface PerformanceInfo { navigationStart: number; domEnd: number; domready: number; onload: number; memory: number; }

const defaultPerformanceInfo: PerformanceInfo = { navigationStart: 0, domEnd: 0, domready: 0, onload: 0, memory: 0, };

const performanceInfo = reactive(defaultPerformanceInfo);
