JavaScript Regular expressions Replacing string match with a callback function
Example
String#replace can have a function as its second argument so you can provide a replacement based on some logic.
"Some string Some".replace(/Some/g, (match, startIndex, wholeString) => {
if(startIndex == 0){
return 'Start';
} else {
return 'End';
}
});
// will return Start string End

"My name is {surname}, {name} {surname}".replace(/(?:{(.+?)})/g, x => data[x.slice(1,-1)]);
// "My name is Doe, John Doe"
