ScreenProps in React

Actually, I haven’t finished the react course of mosh, but I got a bit urgent for my internship project.
I had surveyed it on google but I cannot understand clearly the concept, can someone give me a simple explanation with an example like ‘this.props.screenprops’ refer to? I can’t get understand the program developed by the company, but they currently don’t have other IT staff, I am the only student currently inside the company with my internship :x
