1. Introduction

In this web page there is one web browser JavaScript feature support test: a feature implementation test. The implementation test determines if the web browser recognizes the JavaScript concise method syntax. The implementation test is a simple test for the presence of web browser support, and a definitive test for the absence of web browser support. If the web browser does not recognize the JavaScript concise method syntax, the implementation test reports: Fail (no support): The web browser does not recognize the JavaScript concise method syntax. The web browser does not support the JavaScript concise method syntax. If the web browser recognizes the JavaScript concise method syntax, the implementation test reports: Pass (at least partial/possibly full support): The web browser recognizes the JavaScript concise method syntax. The web browser at least partially/possibly fully supports the JavaScript concise method syntax. Positive determination of full web browser support is beyond the scope of this test.

The web browser support test source code is shown in Section 2.1. The web browser support test source code is run in Section 2.2, which shows the web browser support test result.
