What is the criteria we use to choose the suitable programming language for the next web application?

It depends upon several factors including but not limited to the following:

1. Scalability
2. Flexibility
3. Robustness
4. Exact requirements
5. Responsive
6. Volume of data
7. Graphic content
8. Dynamic or static content

These are few of many factors which helps us to make better decision about what programming language and framework we choose for our next web application. Web programming has two parts one is front end and other is backend. In modern web technologies there are frameworks for front as well as for backend design. For front end we can use HTML5, CSS and JQuery or we can use frameworks such as AngularJS which provides a structured and easy approach for complex web site designs. There are technologies for backend systems such as .NET framework using MVC, PHP etc. One other important factor is money i.e. you wana go for open source or not. The open source hosting servers are less expensive then their counterparts. In current times the most used technologies for web development are ASP.NET using MVC, and PHP.
