Remove the second number from each string in array

I have an array:

[
  '9.18,50',  '108.78,5',
  '80,2',     '9.18,10',
  '108.78,8', '19.12,10',
  '91.16,5',  '19.12,20'
]

and I would like to map through and create a new variable that will have only the first number in each string. Expected output would be:

[
  '9.18',  '108.78',
  '80',     '9.18',
  '108.78', '19.12',
  '91.16',  '19.12'
]

>Solution :

try

let date =[
  '9.18,50',  '108.78,5',
  '80,2',     '9.18,10',
  '108.78,8', '19.12,10',
  '91.16,5',  '19.12,20'
];

const result = date.map(x => x.split(',')[0]);

console.log(result);
