    Your regex does not match only digits, it matches a line of 9 or more non-linebreak chars. What do you mean to do? Please clarify with an example.

You don't need regex to do this. You can use .substr()



Here I used str.substr(0, 9); where 0 is the start of the string you want to keep, and 9 is the length of the portion you want to keep (ie: to the 0+9th index is where it will cut off the string):




let str = "123456789Hello world!";

let res = str.substr(0, 9);

console.log(res);
