Web framework
A web framework is a set of software tools and libraries designed for developing web applications. A framework provides an out-of-the-box foundation for building web applications. It simplifies and speeds up the development process: instead of building a website or application from scratch, a developer only needs to customize an off-the-shelf solution. It's like building a house out of lumber instead of cutting down trees.
Web framework examples
There are many different web frameworks available. Here are some popular solutions.
Django — helps you quickly build web projects in Python. It includes templates for web page caching systems, user permissions management and authentication.
Ruby on Rails — a Ruby framework for server-side applications. It is loved by developers for its security, clear structure, and clean code output. Ruby on Rails comes with a huge library of tools. The framework is used for quite large projects, for example, Twitter, GitHub, Groupon.
Laravel — is one of the most popular PHP frameworks that makes it easy to develop web applications. It includes many UI templates, database tools, and authentication tools.

What web frameworks are good for
Development acceleration: web frameworks offer pre-designed modules, classes, and functions - developers don't have to write code from scratch and can focus on the logic of the application.
Structured approach: Web frameworks make it easier to break applications into modules, manage dependencies, and ensure code homogeneity. This makes projects easier to support and scale.
Security: Many web frameworks provide integrated protection against common vulnerabilities such as cross-site request forgery (CSRF), SQL injection, and XSS. They may also offer tools for encrypting data, handling authentication and authorization.
