How to get a given fragment from a string?

Question

Regular Expressions

Good afternoon! Need help writing a regular expression.

There is this line: test-tes241-text-0123-2-5937-5172473
You need to get this fragment: -5937-5172473 (The format is always the same, just the numbers are different)

ps I need this for a js script, I need to check for the presence data at the end of the line.

Answer 2

While it is calculated to what sign, there is a suspicion that regex is not needed here?
UPD "the numbers are different" - if the number is different, then break it into parts by "-" and take the last two, if the number is the same, then generally just take this number from the end of the line.

Answer 3

You can do without regex, if you know that you need to take exactly two sequences from the end

let s1 = "test-tes241-text-0123-2-5937-5172473";
let s2=s1.split("-");
console.log('-'+s2[s2.length-1]+'-'+s2[s2.length-2]);
