regex validation working on regex101 but not in JS – Javascript

I’m using a regex that validates for an URL. The regex is:

^(https?|ftp)://[^\s/$.?#].[^\s]*$

The issue that I’m getting is that when I check for the validation in regex101. My test cases are getting validated but in my JS code it’s not validating the strings having an "s" in them.

This is the regex and the test cases that are working fine here but not working in my JS code.
I think the issue that I’m facing might be that the "S" characters are being treated as space.

let DestinationRegex = new RegExp('^(https?|ftp)://[^s/$.?#][^s$]*$');
if (DestinationRegex.test("https://atlas.mapmyindia.com")) {
     console.log("Yeahhhhhhh")
} else {
     console.log("Nahhhhlh")
}

I tried this and always get into the else statement whenever I use the string with a S in it.

    Use the same regex directly in the if statement, it works.

    Edit: saved regex in a variable instead of using it directly, for readability.

    let DestinationRegex = /^(https?|ftp)://[^s/$.?#][^s$]*$/;
if (DestinationRegex.test("https://atlas.mapmyindia.com")) {
  console.log("Yeahhhhhhh")
} else {
  console.log("Nahhhhlh")
}

    Try this way, with conctructor it’s a different syntax

    let DestinationRegex= new RegExp(`(https?|ftp)://[^s/$.?#][^s$]`);
const str= "https://atlas.mapmyindia.com";
console.log(DestinationRegex.test("https://atlas.mapmyindia.com"))
if (DestinationRegex.test("https://atlas.mapmyindia.com")) {
  console.log("Yeahhhhhhh");
} else {
  console.log("Nahhhhlh");
}
