React Map<K,V>型でループしてコンポーネントを返したい。

Posted at

表記のとおり、Map型でループしてコンポーネントを返したい場合、

function Qiita(props: { chikyuwaMawaruMap: Map<Date, Unit> }) { 
    return (

//NG   Map<>型でループできる方探してたらforEach があったのでreturn returnで返るのかなと憶測で考えていたけどだめでした。Object.entries() する必要があるみたいです。
 return (
    {props.chikyuwaMawaruMap.forEach((value, index) => {
      return(<JikkoWaSarerukedoReturnSarenai />)
    }}
)
//OK
 {Array.from(props.chikyuwaMawaruMap.entries()).map((entry, index) => {
   Return (<SampleComponent />);
 }}


//FYI
 interface Map<K, V> {
     clear(): void;
     delete(key: K): boolean;
     forEach(callbackfn: (value: V, key: K, map: Map<K, V>) => void, thisArg?: any): void;
     get(key: K): V | undefined;
     has(key: K): boolean;
     set(key: K, value: V): this;
     readonly size: number;
 }
