Why the heck is it always catching?!?! Oh...derp.

thing.js

class Thing {
    doStuffWithFile( file ) {
        return new Promise( ( reject, resolve ) => {
            /*
            do shit...
            */
            resolve(stuff)
        })
    }
}

var thing = new Thing()

thing.doStuffWithFile('someFile')
    .then( () => { 
        console.log("good!") } 
    )
    .catch( (error) => {
        console.log("error", error)
    })
