Discussion on: Array.prototype.map() expects a return value from arrow function

Hopefully you've solved it by now, but it is difficult to address your specific issue as your code formatting is broken.

Possible issues:

• attempting to return an object without wrapping in parenthesis:

// returns object:
() => ({ })
// returns undefined:
() => {}

• missing return statement

() => {
  return ...
}

An arrow function has an implicit return if no braces ({ }) are used. If braces are used and you intended to return an object rather than defined a code block, then you need to wrap the object in parenthesis (({ })).

If you are using an arrow function with map and returning nothing, then you should either use .forEach instead, or add a return value.
