Optional chaining operator support in VSCode
VS Code 1.41 supports optional chaining in both JavaScript and TypeScript files. This support includes syntax highlighting and IntelliSense.
If you are using VS Code 1.41+ and optional chaining is not working as expected, try:
Check your installed extensions. Some of them may not yet understand optional chaining, which could cause errors or bad syntax highlighting
If you are using a workspace typescript version, make sure it is TypeScript 3.7+
You can install JavaScript and TypeScript Nightly, then reopen VSCode.
