Tail-call elimination / optimization is not a Scheme language-specific feature though. Other popular languages have TCO to varying degrees, like C and C++ when using fairly standard compilers like MSVC, GCC, Clang, or ICC [1]. Destructors do get in the way though sometimes. Java/JVM doesn't support TCO, but Kotlin and Clojure make do with special syntax to support tail-recursion (i.e. tailrec, recur). Apparently JavaScriptCore supports TCO for JavaScript [2]. The book makes it sound like TCE is language-specific, but since that book was published, it's spread to many other mainstream languages too.
