Javascript: find out if the URL is equal to a string, with or without trailing slash

Question

I have the following conditional statement in JS:

if(url === 'http://www.productionlocations.com/locations' || url === 'http://www.productionlocations.com/locations/')

I'm trying to make it more efficient so I tried this:

function stripTrailingSlash(str) {
    if(str.substr(-1) == '/') {
        return str.substr(0, str.length - 1);
    }
    return str;
}

theurl = stripTrailingSlash(url);                   
if(theurl === 'http://www.productionlocations.com/locations')

But obviously that just makes it into more code :)

What's the most efficient way of doing this? I had tried using indexOf() before, but it didn't work. Thanks for your help!

The conditional statement does not strip anything. If the stripping is not essentiell, do not do it! — Amberlamps

A simpler way to remove a tailing slash: str.replace(/\\$/, '') — user166390

you can use test method:

if(/^http:\/\/www\.productionlocations\.com\/locations\/?$/.test(url)) {
    // code goes here
}

It makes it hard to see the original test URL, and harder to maintain if the URL changes.

if(/\/locations\/?$/.test(url)) Is totally doable. And accomplishes the same goal.

Yes, if you don't need to check domain.
