Lots of people know jQuery, React, Vue, etc., but they don't know JavaScript itself. If you take away their library, they would be lost. They don't understand how React works and why it's useful. They don't know how and when to use different strategies and methods, because they lack the understanding of how those things work under the covers.
I wholeheartedly agree. I'm myself was and still is the person mentioned above. When I got into frontend I never emphasize on learning Javascript but j just use it as I learn jquery, react, node.
Ignorance/lack of knowledge.
