Visual Studio Code Formatting fail on save

I've started learning React Native.

I'm using Visual Studio Code as my editor.

I've set up the boiler plate and started the app. But whenever I change a .js file and hit save, VSCode is messing up all the formatting.

Is this a bug or am I doing something wrong?

UPDATE: I re-installed vscode. Then set up a basic js file with a react native tag and a html tag. I added in:

"editor.formatOnSave": false,
"javascript.format.enable": false

To my settings.json file and the problem still occurs:

The problem is having tags in a js file, I just don't know how to tell vscode to ignore them?
