Creates a string from a sequence of UTF-16 code units.

Returns
string — A string created from the given code units.
Examples
console.log(String.fromCharCode(72, 105));
Output

console.log(String.fromCharCode(65));
Output

Notes
Works with 16-bit code units, so characters above U+FFFF require surrogate
pairs. Use `String.fromCodePoint` for full code points. It is a static method
on String, not an instance method.
