Learn about the right usage of keys in components; how to render components using conditional evaluation; how to perform conditional rendering using variables; and how to evaluate conditions by using inline logical operators. Explore how to perform rendering with ternary operators; the use of local state in components; and the disadvantages of storing local state. Learn about removing state from lower-level components, and lifting state up to higher-level components. Delve into code reuse by using inheritance and code reuse by using composition. Examine how to use composition to customize child elements and how to create special components using composition. Explore the use of global properties without context, and finally, the use of context to specify global properties.
