Client side and server side coding both have their own advantages and disadvantages when it comes to running a web page.
Client side coding is programming that runs on the user’s computer, such as JavaScript, Flash, and ActiveX. Client side coding gives the user control over the code. However, there are two problems that arise with client side coding. The first problem is client side programming offers greatly reduced control of coding when compared to server side. Second, client side coding is more prone to bugs and other problems that relate to operating systems and web browsers. To make matters worse these two problems add together to make it hard to for programmers to fix them. Issues with the buggy nature of client side coding aside it is also less secure, because hackers can read your information in plain script.
Server side coding may not offer clients control, but it is super in every other way. It reduces bugs, because all the coding is run on one server. It is also far supper at resisting attempts to hack it, because it can be encrypted. This encryption prevents hackers from viewing the code and stealing private information.
When choosing which option is best way your options. Is the personal control that client side coding offers most important or is more reliability and security more important? Once you know the answer for that question you will know which choice is right for you.
