Description: The declarative paradigm is a programming approach that focuses on the ‘what’ rather than the ‘how’. Instead of detailing step-by-step the control flow of a program, the declarative approach allows developers to express the logic of computation in a more abstract way. This paradigm is used in various areas of technology, including programming languages, databases, and infrastructure configurations. In many systems, for example, configuration is done declaratively, meaning users specify the desired state of the system, and the system takes care of implementing those changes. In popular JavaScript frameworks, components are often defined declaratively, allowing developers to describe how the user interface should look based on the application’s state. Infrastructure as code (IaC) also adopts a declarative approach, enabling DevOps engineers to define infrastructure in a way that resembles programming, facilitating automation and resource management in the cloud. This approach not only improves code readability and maintainability but also reduces the likelihood of errors, as it focuses on the end result rather than the intermediate steps needed to achieve it.
