  1. JavaScript だと、、、 x の中身が次々入れ替わる または () が多重になると読みにくい x = 3.14;

    x = Math.round(x); x = String(x); result = x.length; result = String(Math.round(3.14)).length;
  2. Python だと、、、 df = df[df.age > 5] df = df[['name',

    'sex', 'age']] res_df = df.sort_values(by="name", ascending=False)
  3. Elixir だと、、、 res_df = df |> DataFrame.filter(age > 5) |>

    DataFrame.select(["name", "sex", "age"]) |> DataFrame.arrange(desc: name)
