String.fromCodePoint()

The String.fromCodePoint() static method returns a string created from the specified sequence of code points.

Because fromCodePoint() is a static method of String, you always use it as String.fromCodePoint(), rather than as a method of a String value you created.

Unicode code points range from 0 to 1114111 (0x10FFFF). In UTF-16, each string index is a code unit with value 0 – 65535. Higher code points are represented by a pair of 16-bit surrogate pseudo-characters. Therefore, fromCodePoint() may return a string whose length (in UTF-16 code units) is larger than the number of arguments passed. For information on Unicode, see UTF-16 characters, Unicode code points, and grapheme clusters.

Syntax example: String.fromCodePoint()
