String.fromCharCode ( …codeUnits )
Return a string, where each character in string has corresponding codeUnits.
Each of codeUnit should be a integer from 0 to 65535 inclusive.
65535 = 2^16 -1).
If it is greater than 65535, a value of modulo(codeUnit, 2^16) is used.
(it's possible to use
String.fromCharCode() to create a string that contains a character with Unicode codepoint greater than 65535. You have to find the pair of 16 bits values (called surrogate pairs) to form 1 such character.)
Note: most of the time, you probably want
[see JS: String.fromCodePoint]
// convert sequence of unicode codepoint to string console.log ( String.fromCharCode ( 97, 98) === "ab" ); // true // 97 is the codepoint for letter “a” // 98 is the codepoint for letter “b”
// String.fromCharCode won't work as expected if codepoint is greater than 65535 (that's 2^16 ) const tt = String.fromCharCode ( 128514 ); // 😂 // name: FACE WITH TEARS OF JOY // codepoint decimal: 128514 // codepoint hexadecimal: 1f602 console.log ( tt ); // prints , WRONG
