Semicolon Formatter Option

TypeScript’s built-in formatter now supports semicolon insertion and removal at locations where a trailing semicolon is optional due to JavaScript’s automatic semicolon insertion (ASI) rules. The setting is available now in Visual Studio Code Insiders, and will be available in Visual Studio 16.4 Preview 2 in the Tools Options menu.

Choosing a value of “insert” or “remove” also affects the format of auto-imports, extracted types, and other generated code provided by TypeScript services. Leaving the setting on its default value of “ignore” makes generated code match the semicolon preference detected in the current file.
