Filter array with regex using Javascript

I am not very well versed with coding. I have a set of strings in an array and I am trying to filter them out using regex but it's not working for me. I want my result array to return any string containing _number like _0, _01, _000

and the filter that I am using is

var myArray = ["bedroom_01", "bedroom_02", "bedroom" , "bathroom_01"];

var result = myArray.filter(name => name.includes("/_\d+/g"));

console.log(result);

The above code is returning me a blank array. Please let me know what am I doing wrong?

What you are passing to includes is a string not a regexp and includes takes a string not a regexp instead you can use the match method

var myArray = ["bedroom_01", "bedroom_02", "bedroom" , "bathroom_01"];

var result = myArray.filter(name => name.match(/_\d+/));

console.log(result);

You need RegExp#test with a regex literal:

var myArray = ["bedroom_01", "bedroom_02", "bedroom" , "bathroom_01"];
console.log(
   myArray.filter(name => /_\d+/.test(name))
)

If you need to check if the array item ends with _ + digits, use /_\d+$/.
