Returns a string created by using the specified sequence ISO-Latin-1 codeset values.
String
fromCharCode(num1, ..., numN)
num1...numN
A sequence of numbers that are ISO-Latin-1 codeset values.
This method returns a string and not a String object.
fromCharCode is a static method of String. As a result, you always use it as String.fromCharCode(), rather than as a method of a String object you create.
The following example returns the string "ABC".
String.fromCharCode(65,66,67)
