In Java we would use `String.format`. https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#format-java.lang.String-java.lang.Object...- https://docs

  Oh thanks :) I wasn't sure anymore about how I'd do it in Java so I wrote "a language that looks like Java". Took the easy way out instead of having to actually look it up. I'm going to leave it as it is though but good to know ;-)

  String.format is slow compared to normal string concatenation (i.e. "foo" + "bar")! Bit me once when using String.format in a hot path. https://stackoverflow.com/questions/513600/should-i-use-javas-string-format-if-performance-is-important https://stackoverflow.com/questions/513600/should-i-use-java...

    Those benchmarks can't be accurate as they don't use JMH. Edit: i do believe you that + is faster, as it doesn't need to parse the format string, but you should still always do benchmarks with JMH or they won't be accurate.
