I want to become a freelancer in web developing and I learnt HTML CSS and JavaScript for the front-end. What should I learn for the back-end part to make the full web site for my customers?
To become a full-stack web developer, you will need to learn a back-end programming language and a web framework that works well with that language. Some popular back-end languages and frameworks include:
JavaScript: Node.js and Express
Python: Django and Flask
Ruby: Ruby on Rails
PHP: Laravel
You will also need to learn how to work with a database, such as MySQL or MongoDB, to store and retrieve data for your web applications.
Additionally, you should familiarize yourself with version control systems like Git and development tools such as command line interface, text editor, and integrated development environments(IDEs) to streamline your workflow.
You should also learn how to deploy your web application to a web server or hosting service.
Finally, you may also consider learning web security, performance optimization and SEO (Search Engine Optimization) in order to provide a better and complete service to your customer.
