Earlier quoted context omitted.
Yes, and it's missing tons of things we take for granted in other langauges. If you look at the "strings" section it's so short. There aren't even convenience things like string reverse.
Why do you want a string reverse? - Do you want to reverse bytes, or codepoints? - Do you want to reveres codepoints, or grapheme clusters? - Do you really want to reverse grapheme clusters, or do you want to reverse some grapheme clusters while leaving e.g. sequences of control characters in the same order? - Do you really want to reify any of this rather than iterate backwards in the existing memory?

Dart: str.split('').reversed.join();
Java: new StringBuilder().append(str).reverse().toString();
JavaScript: str.split('').reverse().join('');
PHP: strrev($str)
Python: ".join(reversed(str))
Rust: str.chars().rev().collect()
