Wouldn't the following sample code be better? (タプル型の例としては異なる型のペアのほうが例として好ましくないですか？)

Wouldn't the following sample code be better? type Point2D = [number, string];

Certainly! Having different types in a tuple indeed showcases the unique capability of tuple types more effectively. However, including a string in Point2D might seem unnatural, suggesting that a significant change to the example could be beneficial.

ja: たしかに！異なる型同士のほうが、タプル型らしさが出ますね。Point2Dがstringを持つのは不自然なので、例を大きく変える必要はありそうですね。
