So, we know what transpilation is, let's dig a little deeper into what transpilers we have:
First two I already mentioned
styled-components and of course
react are likely to have babel plugins that improve something in one way or another, using a compilation step to get some nice DX or performance improvements. Since version 7 Babel also supports TypeScript which makes it even more powerful.
There is project named
ttypescript that provides this capability by applying custom-made pluggable transforms. It's an amazing option for those projects that are still using TSC as the main compiler without Babel. It will slowly die out because of Babel's popularity and wide support.
