EchoFunction[f][expr]Echo[expr]EchoLabel[][expr]EchoFunction[][expr]EchoLabelは中間結果をラベルを付けて出力する:
expr1;x = EchoLabel["factors:"]@FactorInteger[2 ^ 50 - 1];expr2中間結果の特性が出力したければEchoFunctionを使うとよい:
expr1;x = EchoFunction["factors:", Length]@FactorInteger[2 ^ 50 - 1];expr2QuietEcho[EchoLabel["label:"][expr]]関連するガイド
