1 Introduction

Microsoft web browsers support ECMAScript Internationalization API Specification [ECMA-402], Standard ECMA-402 1st Edition / December 2012, with no variations, clarifications, or extensions.

The supported specification provides key language-sensitive functionality as a complement to the ECMAScript Language Specification, 5.1 edition or successor. Its functionality has been selected from that of well-established internationalization APIs such as those of the Internationalization Components for Unicode (ICU) library, of the .NET framework, or of the Java platform.
