React code is made of entities called components. [14]: 10–12 These components are modular and can be reused. [14]: 70 React applications typically consist of many layers of components. The components are rendered to a root element in the DOM using the React DOM library.
A reflected attack is typically delivered via email or a neutral web site. The bait is an innocent-looking URL, pointing to a trusted site but containing the XSS vector. If the trusted site is vulnerable to the vector, clicking the link can cause the victim's browser to execute the injected script.

[15] Variations of the "Hello, World!"
Similarly, because dependency injection does not require any change in code behavior, it can be applied to legacy code as a refactoring. This makes clients more independent and are easier to unit test in isolation, using stubs or mock objects , that simulate other objects not under test.
