How to split a specific part from String(Javascript)?

Question

Given the three formatted distance strings, how can I extract just the distance number?

x = "Max, 156km from you(001)"
a = "Nick, 66km from you(131)"
b = "Niclas, 76km from you(224)"

console.log(distance_from_x, distance_from_a, distance_from_b)
// Expected: (156,66,76) 

Answer 1

This should work

const regex = /[0-9]+km/gm;

Answer 2

You can use this regular expression:

(\\d+)km
