    String.fromCharCode Redirect 1

    Summary

    The static String.fromCharCode() method returns a string created by using the specified sequence of Unicode values.

    Syntax

    String.fromCharCode(num1, ..., numN) 

    Parameters

    num1, ..., numN
    A sequence of numbers that are Unicode values.

    Description

    This method returns a string and not a String object.

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

    Examples

    Example: Using fromCharCode

    The following example returns the string "ABC".

    String.fromCharCode(65,66,67)
    

    Getting it to work with higher values

    Although most common Unicode values can be represented with one 16-bit number (as expected early on during JavaScript standardization) and fromCharCode() can be used to return a single character for the most common values (i.e., UCS-2 values which are the subset of UTF-16 with the most common characters), in order to deal with ALL legal Unicode values (up to 21 bits), fromCharCode() alone is inadequate. Since the higher code point characters use two (lower value) "surrogate" numbers to form a single character, String.fromCodePoint() (part of the ES6 draft) can be used to return such a pair and thus adequately represent these higher valued characters.
