Document Object Model(DOM)

Document Object Model(DOM)

Hi dev,

In this article we will learn about Document Object Model (DOM) in javascript.

HTML document is structured as a JavaScript Object. Every HTML element has a different properties which can help us to manipulate it. It is possible to get, create, append or remove HTML elements using JavaScript.

When it comes to React we do not directly manipulate the DOM instead React Virtual DOM will take care of update all necessary changes.

So do not directly manipulate the DOM if you are using react. The only place we directly touch the DOM is here at the index.html. React is a single page application because all the components will be rendered on the index.html page and there will not be any other HTML in the entire React Application. You don't have to know DOM very well to use react but recommended to know.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <title>Javascript App</title>
  </head>

  <body>
    <!-- <div class="root"></div> -->
    <div id="root"></div>

    <script>
      // const root = document.querySelector('.root')
      // const root = document.getElementById('root')
      const root = document.querySelector('#root')
      root.innerHTML = <h1>Welcome to opencodesolution Of Javascript </h1>
    </script>
  </body>
</html>

 

Hope it can help you…
