I wanted to update my javascript code to the new ES6 Standard, so I looked at how functions are now written and tried it out on a global function of mine, which reads like this in the old es5

function logMessage(message) {

    document.getElementById(logs).innerHTML = document.getElementById(logs).innerHTML + `<li  class=item-padding>  ${message} </li>`

}

now if I'm not wrong the correct transformation to ES6 would be like this:

logMessage = message => {

    etc

}

But my ESLint tells me that my logMessage is not defined and I get an error in my console, do I miss something? Do I have to declare var, let or const before the logMessage?

I don't know if its important, but I also want to export this function from file One to file Two and use the function logMessage in another function in file Two, is there something I have to keep in mind when doing so?

Thanks for any help!

Edit: Thanks everyone the answers helped me a lot, got my problem fixed!
