Semicolon-Aware Code Edits
Editors like Visual Studio and Visual Studio Code can automatically apply quick fixes, refactorings, and other transformations like automatically importing values from other modules.These transformations are powered by TypeScript, and older versions of TypeScript unconditionally added semicolons to the end of every statement; unfortunately, this disagreed with many users’ style guidelines, and many users were displeased with the editor inserting semicolons.
TypeScript is now smart enough to detect whether your file uses semicolons when applying these sorts of edits.If your file generally lacks semicolons, TypeScript won’t add one.
