Record<string, string>如何删除里边的元素

export function mapToRecord(myMap:Map<string,string>):Record<string,string> { 
  return Object.fromEntries(myMap.entries()) as Record<string, string>; 
} 
 
export function recordTomap(myRecord:Record<string,string>):Map<string,string>{ 
  let myMap:Map<string,string> = new Map() 
  for (const key in myRecord) { 
    myMap.set(key, myRecord[key]) 
  } 
  return myMap 
} 
 
在ets 中实现增删修改 
let res:Record<string, string> = {“fod” : “1” , “bard” : “2”} 
let myMap:Map<string,string> = recordTomap(res) 
 
myMap.set(‘func’,‘3’) 
 
let myRecord = mapToRecord(myMap) 
 
console.log(JSON.stringify(myRecord))
