The typescript compiler has an "allowJs" option. However .js files are not part of the project so compileOnSave will not be triggered for the .js files.
I had a look at TSIndexerFactory:: createIndexer() and found that it would only index tsconfig.json and *.ts files.
If it also indexes all .js files or just the .js files specified inside the files tsconfig option. compileOnSave would work for the include *.js files as well.
