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.
