I am currently working on getting data from an API, and I want to remove some characters from what it returns.

What I get back is `{"usd":323.67}`, but the currency and price may change depending on the input.

I want to remove the {}, usd (or other currency), "" and :. I searched, and found `.replace()` could be a good solution, if you replace the character with nothing. But when I use `.replace(""", "");`, I of course get an error. When I do, `.replace("{}", "");`, it doesn't replace the {} with nothing either. And because I use a constant for the currency, because the user can choose, the currency it not always the same, so I thought it could use `.replace(`${currency}`, ""), but that also doesn't work.

What should I do to remove these things from my string?

Thanks in advance!
