Visual Studio Code:[js] types can only be used in a .ts file

Is it possible to use .js files in a typescript project in vs code? I have clone a react-native project from a github repository and opened it in visual studio code. When I add a tsconfig.json in order to start using typescript, I get a long list of errors. For example here is a drawer.js file (with es6 features):

Here is my tsconfig.json file (If I remove this file then every thing works fine, no error reported) :

NOTE - This is just a WORKAROUND, not solution. Use ONLY IF you do not find appropriate solution

Workaround - Add the following configuration in $workspace/.vscode/settings.json

{
    "javascript.validate.enable": false
}
