arrow function doesnt get binded with this.previous
sirpy opened this issue · comments
When using an arrow function:
(userId,doc..) => {}, this.previous is not defined
function(userId,doc...) {} works just fine
Yeah, that's how arrow functions work... Arrow functions don't have their own this and can't be given (bound) a new this value, it always uses the this in the context of where it was defined.
