There are a lot pros and cons of diffrent typing, yet on the one hand static typing wins – security.

- find a victim. Website with on-line shop.
- Pick your laptop and start the order
- In this process fill out the amount textbox with value ‘.1’ (dot and one)
Since most of the systems calculate the final value of bill :
ValueOfOneLaptop x AmountOfLaptops = TotalAmount
If there is no valiadtion upon floating point TotalAmout will be 10% of a laptop’s value. How? .1 stands for 0.1 and therefore 0.1 gives you 90% discount :). Most likely shop engine is wirtten in PHP or Python so you have a lot of chance to get it pass through. A shop employee validates the order and will not spot the little dot.
Brilliant isn’t it?
Web Devs need to bare in mind this.
Static vs Dynamic 1:0.
