From a9bf6652b5353f2098d4c0cd0eb77d17e02e164d Mon Sep 17 00:00:00 2001 From: Ruben Bridgewater Date: Tue, 26 Mar 2019 15:53:11 +0100 Subject: util: use minimal object inspection with %s specifier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This improves `util.format()` by returning more meaningful results when using `%s` as specifier and any object as value. Besides that `BigInt` will also be represented with an `n` at the end to indicate that it's of type `BigInt`.
