the input variable looks like this :
[ { message: 'Cillum quis laborum incididunt aliqua est et consectetur ipsum
elit d
eserunt.' },
{ message: 'Dolor incididunt velit sit deserunt laboris sunt nostrud cillum
Lorem
sit occaecat dolore aute ex.' },
{ message: 'Id fugiat veniam do eu.' },
{ message: 'Consequat id non nulla culpa dolore eu irure deserunt.' },
{ message: 'Mollit qui elit tempor eiusmod eu.' },
{ message: 'Aliquip quis aute cupidatat adipisicing irure nisi consectetur.'
},
{ message: 'Adipisicing ea cupidatat quis sunt eu id velit voluptate officia
cill
um elit aute aliqua.' },
{ message: 'Qui incididunt aute eiusmod Lorem cillum.' },
{ message: 'Sunt non ut eiusmod id magna sunt culpa labore aliquip.' },
{ message: 'Mollit exercitation sunt esse reprehenderit consequat laboris
irure i
n dolore non.' },
{ message: 'Incididunt Lorem minim non sunt est mollit non do nulla elit qui
ipsu
m.' },
{ message: 'Ea exercitation occaecat nulla irure eiusmod pariatur enim ipsum
duis
pariatur pariatur.' },
{ message: 'Consequat ad labore occaecat magna.' },
{ message: 'Sunt commodo veniam consequat ea exercitation incididunt esse
nostrud
elit labore ipsum aliquip.' },
{ message: 'Do deserunt consectetur id pariatur culpa.' },
{ message: 'Magna consectetur irure consequat duis consequat dolore duis
exercita
tion eiusmod id aute exercitation.' } ]
Maybe on some way use the map function so every item in the array is used. ?
