How can I obfuscate JavaScript?

I was browsing some sites and found really interesting thing. I am just starter in this coding and never seen such a thing, so I was wondering is it encrypted or encoded or packed or is there anything else?

Script sample:

V10861992380165541086199238016554108619923801655410861992380165541086199238016554108619923801655410861992380165541086199238016554='13047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395130473894741439513047389474143951304738947414395'

Can anyone tell me what are these, and how can I do the same?
Do I need to pay for an program or something? Thank you for understanding.

Answer 1

All the line or code does is create a variable starting with V and put the number in it. Without seeing the rest of the code I cant tell if it is just encoded or encrypted as well, but if you notice the string is just repeating the number 1304738947414395.
You can definitely do a simple encoding by your self. A simple encoding is to put all the javascript code in a string like aaa="document.write('blah')" and then say aaa="atob(aaa) which converts the original string to base64. Save the base64 string and then place it in an eval statement like eval(btoa(aaa)) that converts it back to text, and then the eval executes the text. When it’s finished you have some encoded mildly obfuscated code.
