I'm beginner React developer and have syntax error when I start yarn in atom.

I didn't edit any code before I first started yarn, but it has a syntax error. I have successfully run create-react-app using nvm and yarn in my local terminal.

This is error log in atom terminal

question Which command would you like to run?: start
$ react-scripts start

  • You can't apply `async` to an arrow function that way. Check this answer: https://stackoverflow.com/a/42964310/751484 – Jonathan M Apr 02 '19 at 14:30

    @JonathanM That's not correct. The [syntax is fine](https://jsfiddle.net/jrunning/peqwcmn2/3/) for an `async` arrow function with a single argument. The error message suggests, rather, that OP is running an old version of Node that doesn't support `async`/`await` at all. – Jordan Running Apr 02 '19 at 20:51

Update your node version to at least v8 and it should run perfectly
