Having trouble with the "\\" not working? Is there a way to use just one backslash instead?

I'm struggling with a little issue in Typescript - how can I use just one backslash?

What I'm aiming for is an url pattern like this: 

"\/hello\/"+ urlRoute + "\/([0-9]*)"
,

But when I attempt it, I end up with 

"/hello/"+ urlRoute + "/([0-9]*)"

If I try 

"\\/hello\\/"+ urlRoute + "\\/([0-9]*)"
,

The result is 

"\\/hello\\/"+ urlRoute + "\\/([0-9]*)"
,

I've tried some solutions without success - I always end up with two or three backslashes, never just one ^^

If anyone has any insight or advice,

I would appreciate the help. Thanks!

Here's a helpful tip: Make use of template strings for easier string interpolation! Check out this link for more information: https://basarat.gitbooks.io/typescript/content/docs/template-strings.html

Despite that, your code is functioning correctly as shown below:

let urlRoute = "something"; 
console.log("\/hello\/"+ urlRoute + "\/([0-9]*)" == `/hello/something/([0-9]*)`); // prints true
