JavaScript のアロー関数の書き方

Posted at

自分はあまりコードは書きません。
色々記法があって忘れがちなのでメモします。

アロー関数

アロー関数のメリット

1.関数を簡略化できる
2.thisを束縛できる

アロー関数の例

const CalcSum = (a,b,c) => {
const result = a + b + c;
return result;
}
const myFuntion1 = (a) => {
 return a + 2;
})
const myFunction2 = a => {
 return a + 2;
});
const myFunction3 = (a) => a + 2;
