Study Notes

Programming Paradigms

  • Procedural Programming: Emphasizes a linear, top-down approach for problem-solving.
  • Declarative Programming: Utilizes a domain-specific language (DSL) to specify tasks without detailing the control flow.

Debugging Tools

  • Integrated Development Environment (IDE): Essential for code debugging; provides features like code compilation and debugging tools.

IDE Features

  • Built-in Functions Library: Increases coding efficiency by offering pre-made functions.
  • Autocomplete: Suggests and completes keywords to speed up the coding process.

Application Development

  • API Usage: Essential for integrating third-party features, such as custom Google Maps on a website.
  • Cross-Platform Development: To create applications for both Windows and iOS, leverage the APIs specific to each operating system.

Python Programming

  • General Purpose Language: Python is popular for web and mobile app development, known for its readability.
  • Input/Output Operations: Python can receive inputs and produce outputs through simple code.
  • Random Function: Accessed with import random, enabling the use of functionalities that generate random numbers.

Programming Languages for Web Development

  • Interactive Elements: JavaScript is the preferred language for adding interactivity to websites.
  • JavaScript Functionality: A basic JavaScript snippet displays text and buttons on web pages.

Developer Roles

  • Front-End Developer: Focuses on the visual and aesthetic aspects of a website.
  • Back-End Developer: Manages database access, ensuring secure information handling.

HTML Document Structure

  • Essential HTML Tags: <!DOCTYPE html>, <html>, <head>, and <body> are required for a complete HTML document.
  • Document Metadata: The <head> section contains the title, style links, and important metadata for search engines.

HTML Elements and Syntax

  • Interactive Elements: JavaScript enhances user interactivity on web pages.
  • Document Structure Tags: HTML contains structural tags indicating content like headings and lists.
  • Hyperlink Syntax: <a href="https://testout.com">Link to the TestOut homepage</a> is the correct syntax for creating hyperlinks.

Lists in HTML

  • Numbered List Tags: Use <ol> for ordered lists along with <li> for list items.

Headings in HTML

  • Heading Levels: HTML supports six levels of headings (<h1> to <h6>), allowing for structured content hierarchy.
  • Visual Content Elements: The <body> tag encompasses all elements displayed on a webpage.
