Separating out Regex in JS

Question

const url = "./index.js mongodb://localhost:27017/docs find betty";

docs is my database name

const db_name = ? 
const url = ?

How do I separate out the database name using regex in one variable, and the url in another?

Any help is highly appreciated.

Use group matches to define the characters you want to capture:

const input = "./index.js mongodb://localhost:27017/docs find betty";

const regex = /(mongodb:\/\/\w*(\:\d{1,5})?\/(\w*))/;

const url = input.match(regex)[1];
const db_name = input.match(regex)[3];

console.log(url);
console.log(db_name);
