It not format code correctly, and only format partially. **source file**  **sublime jsFormat formated**  **vscode formated**  You see, It seems like, vscode only add some spaces around brackets, letters, commas etc. See https://github.com/Microsoft/vscode/issues/8914#issuecomment-231978337 and the discussion below for more details. The provided traces clearly show that the tsserver only returns white space (" ") changes. No insertion of new lines.
