When you come across the term “declarative approach” in relation to React, it refers to the way React allows you to build user interfaces (UIs).
React made the declarative approach popular in the frontend development world by introducing it as a fundamental concept. However, it is not a completely new concept.
In comparison to using HTML templates, React takes the declarative approach to a whole new level. With React, you can create web interfaces without directly manipulating the DOM. Additionally, you can implement an event system without the need to interact with DOM events.
In contrast, an imperative approach involves tasks like searching for elements in the DOM using jQuery or working with DOM events. In this approach, you explicitly instruct the browser on what actions to perform instead of solely specifying your desired outcome.
React simplifies this process by abstracting these tasks. Instead of directly manipulating the DOM or handling DOM events, all you need to do is inform React about the desired rendering of a component. React takes care of all the interactions with the DOM so you can focus on creating UIs without worrying about low-level details.
By embracing the declarative approach, React allows developers to express their intentions rather than specifying every step of the process. This makes the development process more efficient and less prone to errors.
