a building block that represents a reusable piece of the user interface. components can be combined to create more complex components.
Reusability − Components are usually designed to be reused in different situations in different applications. However, some components may be designed for a specific task.
Replaceable − Components may be freely substituted with other similar components.
Not context specific − Components are designed to operate in different environments and contexts.
Extensible − A component can be extended from existing components to provide new behavior.
Encapsulated − A A component depicts the interfaces, which allow the caller to use its functionality, and do not expose details of the internal processes or any internal variables or state.
Independent − Components are designed to have minimal dependencies on other components.
Component-oriented software design has many advantages over the traditional object-oriented approaches such as −
Reduced time in market and the development cost by reusing existing components.
Increased reliability with the reuse of the existing components.
properties
They are used to provide data or configuration to a component, allowing the component to render based on the provided informaion
data is passed from parent to their child components in a one-way direction ensuring that the parent component remains the source of truth for the data
