What is the correct way to check for String equality in Typescript (for Angular 4)

Question

In Angular 4, I want to check for the current url and if it is equal to "/login" I need to submit a specific form. Here is the code:

 let responseString=this.router.url;
 console.log(responseString);
 if (responseString.match("/login")==null)
   this.submitForm();

The above code does not submit the form in all cases. There is something wrong with the if condition I guess. Any clues?

For simple string-to-string equality, you can use the === operator.
