Comments In JavaScript

Every good programmer comments their code, so if anyone has to edit the code they know what is happening. There are a lot of times you may be the person writing the code, and come back later and think what was I doing here. If you have very well commented code, then this reduces some of that confusion. To comment out code you could use /* and */, everything in between the two will be ignored by the browser. This type of comment system is used when creating multiple line comments. You can also use a double backslash for single line comments.

<language="JavaScript" type="text/Javascript">
 /*This is my first script. 
   I think I should start by
   telling the world welcome.*/

 document.write("Welcome World.")

 // Done greeting the world.

</script>
