Javascript DOM

When i run it, theelement h1, stays the same. It does not change to hello world... why is it so? <html> <head> <title>Practice JS</title> <script> var elem = document.getElementById("hello"); elem.innerHTML = "Hello World!"; </script> </head> <body> <h1 id="hello">Shameer</h1> </body> </html>

Try to insert your script in the end of the document (before closing tag </body>). You try to change the DOM when is not loaded

Yes, it can. But better practice is make external file.js and put link on it in the head section with attribute async or defer. Example: <script defer src="example.js"> or <script async src="example.js">

So javascript code can be put in the body as well? as long as the code is in a script element? and thank you.
