在性能方面更优选Javascript和jQuery或PHP给出相同类型的工作[关闭]

Description :

I have couple of functions that can be written in JavaScript and PHP aswell.

e.g

(a) Current datetime calculation and their subtraction

(b) String replace , extracting substring , checking for a position of character in string and many more

I can submit the data in two ways either I can perform all the calculations and functions on client side using JavaScript

OR

I can send all the raw data to php and do the exact same work in PHP there before saving it in the database.

My Question :

What should I focus on more and try to write as much as I can in either of the languages ?

    If performance is what you're after, do as much as you can in javascript, because client's computer tends to have more free computing power than your server. That is because a client only has to do it for himself, server would need to do it for all visitors - possibly thousands upon thousands. Expected client base is a major factor here.

    However, take into consideration that a client can't be "trusted"; if you're going to insert something in database, verify everything that needs to be right.

    If supporting visitors without javascript is something you'd care to do, you obviously have to move everything server side, but that is rarely the case nowadays.
