Study Notes

Front-End Development

  • Front-end development focuses on the visible aspects of a website or app
  • This includes layout, colors, text, buttons, images, animations, and how elements react to user interaction
  • The goal is to make sites visually appealing, interactive, and user-friendly

Front-End Technologies

  • HTML: Provides the structure of web content (headings, paragraphs, images)
  • CSS: Styles the content (colors, fonts, layout)
  • JavaScript: Enables interactive elements (e.g., button clicks, showing/hiding content)

Common Front-End Frameworks

  • React, Angular, and Vue.js are popular frameworks that enhance interactivity and responsiveness of websites

Back-End Development

  • Back-end development handles the "invisible" parts of a website
  • It manages data storage, business logic, security, and server configuration
  • Crucial for website functionality but not directly seen by users

Back-End Technologies

  • Programming languages used for back-end logic include Python, Java, PHP, and Ruby
  • Databases like MySQL, MongoDB, and PostgreSQL store and manage data like user accounts and settings
  • Frameworks such as Express (Node.js), Django (Python), ASP.NET (C#), and Spring (Java) help organize and structure the code

Example of Back-End Functionality

  • User login: The server verifies credentials, checks username/passwords, and authorizes access to the user's account

Full-Stack Development

  • Full-stack developers handle both front-end and back-end tasks
  • They are skilled in both designing the user interface and managing the server-side logic and data storage

Full-Stack Goal

  • Full-stack developers build complete, functional web apps—from design to data management

Full-Stack Example

  • Building a blog site involves creating the layout, applying styles, handling interactions, and setting up the database to store articles and user data. The process also includes user login and data management features

Frameworks (General)

  • Frameworks are toolkits or libraries that simplify back-end development
  • They offer pre-written code, templates, and libraries
  • Frameworks handle requests from the front-end, manage databases, implement security measures, and structure applications
