実験的なパイプライン演算子 |> (現在はステージ 1 です) は、式の値を関数に接続します。これによって、読みやすい方法で一連の関数呼び出しを作成することができます。結果的に、単一の引数を用いた関数呼び出しの糖衣構文となり、次のように書くことができます。

- -
let url = "%21" |> decodeURI;
- -

これと等価な従来の構文は次のようになります。

- -
let url = decodeURI("%21");
-
- -

構文

- -
expression |> function
-
- -

指定された expression の値が function に、単一の引数として渡されます。

- -

引数

- -
-
expression
-
任意の式です。
-
function
-
任意の関数です。
-
- -

例

関数呼び出しの連結

- -

パイプライン演算子は、複数の関数の連結を読みやすくすることができます。

- -
const double = (n) => n * 2;
-const increment = (n) => n + 1;
-
-// パイプライン演算子なし
-double(increment(double(double(5)))); // 42
-
-// パイプライン演算子あり
-5 |> double |> double |> increment |> double; // 42
