Web development is the process of creating websites and web applications. It encompasses a wide range of skills and technologies1 necessary to build functional and attractive web pages accessible to users via the internet.

Core Concepts of Web Development:

• Programming Languages: HTML, CSS, and JavaScript are the three core programming languages used to create web pages.
  • HTML (HyperText Markup Language): This is the markup language that defines the structure and content of a web page.
  • CSS (Cascading Style Sheets): This is the style language responsible for the visual presentation of a web page, including colors, fonts, layout, etc.
  • JavaScript: This is a programming language that adds interactivity to web pages, making them more dynamic and functional.
• Server-Side: The server-side of web development is responsible for data processing, application logic, and interaction with databases.
  • Programming Languages: PHP, Python, Java, Node.js are popular programming languages used for server-side development.
  • Frameworks: Laravel, Django, Spring Boot, Express.js are frameworks that provide a ready-made structure to simplify server-side development.
  • Databases: Databases are used to store and manage web application data. Popular DBMS include MySQL, PostgreSQL, MongoDB, Oracle.

Key Technologies of Web Development:

• Front-End:
  • JavaScript Libraries: jQuery, React, Vue.js, Angular are JavaScript libraries that simplify the development of interactive web interfaces.
  • CSS Preprocessors: Sass, LESS are languages that allow writing more organized and concise CSS code.
  • Development Tools: Chrome DevTools, Firefox Developer Tools are browser-based tools that help debug and optimize web pages.
• Back-End:
  • Database Frameworks: ORM (Object-Relational Mapping) are design patterns that simplify the interaction between application objects and databases.
  • Content Management Systems (CMS): WordPress, Drupal, Joomla! are platforms that facilitate the creation and management of websites without deep programming knowledge.
• Security: HTTPS, SSL/TLS, CSRF, XSS are technologies that ensure the security of websites and protect user data.

Conclusion:

Web development is a dynamic and constantly evolving field. To create successful websites and web applications, it is necessary to continuously learn new technologies and improve your skills.
