I am trying to group the array by testing them using regex. but getting no result
how this scenario handled?
my reg pattens are there in the object key.
const array = [{
label: '(GMT) Africa/Asmara',
name: 'Africa/Asmara',
},
{
label: '(GMT) Monrovia, Reykjavik',
name: '(GMT) Monrovia, Reykjavik',
},
{
label: '(GMT) Lisbon',
name: '(GMT) Lisbon',

{
label: '(GMT) Greenwich Mean Time : Edinburgh, London',
name: '(GMT) Greenwich Mean Time : Edinburgh, London',

{
label: '(GMT 3:0) Africa/Asmara',

label: '(GMT 2:0) Africa/Bujumbura',

You can add .startsWith() or .includes() in here. Regexp is just going to make it more and more hectic.
