Question

What is the purpose of the basic validation?

(a) Data correctness

(b) Mere data existence

(c) Both Data correctness and Mere data existence

(d) Data modification

I got this question in an online quiz.

My doubt stems from Validation topic in section Caching, Debugging and Animation of JavaScript

Answer 1

Right option is (b) Mere data existence

Easy explanation: The data entered through the server side is used for validation. First of all, the form must be checked to make sure data was entered into each form field that required it. This would need just loop through each field in the form and check for data.
