Usually you would use bold like that where you would stress the vocalisation when reading it aloud, not for highlighting key points you want to make. If you read that and stress those words it just sounds weird and confusing.

That comma placement is strange too. I'm thinking not a native english speaker. It's a great tool though. Not taking away from that at all. Thanks for making it. :)
In the spirit of providing feedback to help improve the documentation, and with regard to the bold text:
The article made it difficult to find out what React Storybook is quickly.
The style of article is informational, which is usually written like a pyramid. High level information at the top, then works into more detail-oriented sections, most important first. For example, "any react application" would probably come in the second paragraph, after the high level intro as that was an important point (based on the repetition) in the bullets.
I used it for highlighting points. I think I am over using it. Will minimize it.
