JS: Decimal and Hexadecimal

This is pretty interesting how you can convert not just standard decimal or hexadecimal numbers but any number with a base between 2 and 32. Here’s how:

var myDecimalNum = 10; 
myDecimalNum.toString(16); 

// result : a

var myHexNum = "a"; 
parseInt(myHexNum,16); 

// result : 10

And not just base 16 (hex), you can do it for any base. Try different bases and have fun.
