  • When you build an application in ReactJs you will have to split the UI into reusable components and think about each of them in isolation.When the user interacts with our application in ReactJs, for example, by hovering, pressing a key, clicking… These actions trigger many other events on the UI…
  • So, why is understanding lifecycle methods so important?Let’s imagine that you are building an application in ReactJs, for example, a video player app, like Vimeo, Twitch or Youtube .
  • Now, your user is using the player app on his/her laptop and decides to search for a fun video to watch, found the video, and then selected to watch it.Let’s suppose that the player app is consuming only resources like network data and the battery power.After some time watching videos…
  • When we build an application in ReactJs , we can predict different type of actions by the user, placing some hooks and triggers.These triggers and hooks are available by component lifecycle methods in Reactjs.
  • They will help us to create the most efficient piece of the software as possible.To place correctly the hook methods into the components we need to learn more about the four stages of ReactJs component.The ReactJs component goes through the Four following is a little diagram to demonstrate those phases.InitializationIn…

Components are the core of ReactJs. When you build an application in ReactJs you will have to split the UI into reusable components and think about each of them in isolation. When the user interacts…

Why Use #React #JS for Fast Interactive User Interfaces?  #reactjs #webdev #javascript #jsx

  • The Virtual DOM is at the core of what makes React fast at rendering user interface elements and their changes.
  • Each time there are changes to the underlying data in a React app, React creates a new Virtual DOM representation of the user interface.
  • This is where efficient diff algorithms, batching DOM read/write operations, and limiting DOM changes to the bare minimum necessary, make using React JS and its Virtual DOM a great choice for building performant apps.

    Although some would argue that all projects need React JS, I think it’s uncontroversial to say that React would be a great fit for web apps where you need to keep a complex, interactive UI in sync with frequent changes in the underlying data model.

    If you’re curious about how React JS and its Virtual DOM work, here’s where you can learn more:

    Conclusion
    React JS and other similar JavaScript libraries ease the development of snappy, event-driven user interfaces that are fast at responding to state changes.

Maria Antonietta Perna discusses what makes React JS a great fit for building fast UIs and introduces the concept of the Virtual DOM and how React uses it.
