TS/JS split part of a string from regex match

In the past, I had this regex:

\{(.*?)\}

And entered this string:

logs/{thing:hi}/{thing:hello}

Then I used the following:

console.log(string.split(regex).filter((_, i) => i % 2 === 1));

To get this result:

thing:hi
thing:hello

For irrelevant design reasons, I changed my regex to:

\{.*?\}

But now, when using the same test string and split command, it returns only this:

/

I want it to return this:

{thing:hi}
{thing:hello}

How can I modify the split (or anything else) to do this?

Why not use match?

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/match

The match() method retrieves the matches when matching a string against a regular expression.

If you're only interested in returning the two string matches then it's much simpler than using split.

var foo = "logs/{thing:hi}/{thing:hello}";
console.log(foo.match(/{.*?}/g));
