Reports usages of a trailing comma in object literals.

The warning is reported only when the JavaScript language version is set to ECMAScript 5.1.

Trailing commas in object literals are allowed by the specification, however, some browsers might throw an error when a trailing comma is used.

You can configure formatting options for trailing commas in Code Style | JavaScript or TypeScript | Punctuation.
