Regex Is Awesome, I am learning regex.

A good Example is to make a simple symbol & space detector with RegEx!
You can use RegExp in javascript

Use \W in RegExp to detect symbols & spaces.
& use .match() in Javascript to search for the symbols.

A RegExp is can be written as a pattern: /\W/g

Example In Javascript 
   var text = prompt("Enter a Name (symbols & spaces not allowed!)"); // Take user Input.
   if(text.match(/\W/g) == null){ // Check if there are spaces, symbols.
     alert("Good Name!!"); // If valid.
   }else{
     alert("Bad Name!! Remove Those Spaces And Symbols!"); // If Invalid
   }
