New string features in ECMAScript 6
The blog post covers new features of strings in ECMAScript 6 (ES6). Unicode code point escapesÂ Â # Unicode â€œcharactersâ€ (code points) are 21 bit long [1]. JavaScript strings are (roughly) sequences of 16 bit characters, encoded as UTF-16. Therefore, code points beyond the first 16 bits of the code point range (the Basic Multilingual Pane, BMP) are represented by two JavaScript characters. Until now
