you are right. I have misread the challenge
Still one problem :
The output now looks like this :
~~~
[ { message: 'Cupidatat reprehenderit qui dolor ex labore amet.' } ,
~~~
where the output must look like this :
~~~
[ message: 'Cupidatat reprehenderit qui dolor ex labore amet.' ,
~~~
So I think I need to use map to fetch the messages one by one or is there
another way .
