Why does Babel not provide URLSearchParams polyfill for IE11

Question

I'm using Webpack + Typescript + Babel with Babel-Loader. Config useBuiltIns: 'usage'

In my code I have some places where I use URLSearchParams. But it seems that Babel is not polyfilling UrlSearchParmas for IE11. I thought I do not worry about any polyfills with babel. (Other polyfills are working for IE11) Is that a normal behaviour or is there something wrong in my code?

I'm not importing anything on my files using URLSearchParams. Maybe babel can not recognize it for this reason?

Answer 1

I've asked the question directly on babel github page. corejs3 will include a polyfill for url search params. Somebody need to review the PR to update corejs3 in babel.
