PHP and Classic ASP are server-side scripting languages. What is wrong with having a website written in this instead of the trendy JavaScript Frameworks like React, Angular etc.? If memory serves me correctly, there is an issue with security where you can post in a text box some script and hack into a system.Can we please discuss some pitfalls or drawbacks to having a website written entirely in PHP or ASP? What does a JavaScript framework or Node.js bring to the table that would otherwise be lacking?I am just now venturing into a contract where I am tasked with updating and maintaining existing code. All I know right now is that it is written in PHP and Classic ASP. I am in the process of investigating these scripting languages and I want to know what the opinion of other developers are.
