Learn about the various properties and methods of the JavaScript String object.
The String object has a static method called String.fromCharCode()
that allows you to create a string representation from a sequence of Unicode characters. You can use this method to build a simple string using ASCII codes.
Example:
String.fromCodePoint(70, 108, 97, 118, 105, 111) //'Flavio'
You can also use octal or hexadecimal numbers:
Example:
String.fromCodePoint(0x46, 0154, parseInt(141, 8), 118, 105, 111) //'Flavio'
All the other methods described in this article are instance methods, meaning they are run on a string type.
