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
