Please cosnsider me as beginner. if you think this question is stupid, sorry for that

1. I added html file in react js as "num.html"
2. In that "num.html", it has tag.
3. I want to use that html file in my react component. so, i rendered in my app component.
4. it was showing error like :

ERROR in ./src/num.html 1:0

Module parse failed: Unexpected token (1:0) You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

5. I want to use script tag on that html file . but react js not allowing. is there any alternative?
