Study Notes
Programming Fundamentals
- After completing this lesson, you will be able to:
- Understand web development and differentiate between a website and a web application
- Create a static website using HTML/CSS in an appropriate environment
- Create dynamic websites using JavaScript as the front-end scripting
- Implement common algorithms that use sequence, selection, and repetition in JavaScript
- Determine ways of debugging their code in JavaScript
Unit 3 Introduction
- The World Wide Web (WWW) was developed to make sharing information easier
- It is becoming increasingly prevalent
- Documents, pictures, audio, video are prevalent types of information
- Social media increases links and tags for sharing information on the internet
- Websites can be dynamic, allowing for changes based on user input
- HTML is a primary language used in website development
- Websites are made up of webpages and accessible via URL
- Search engines are useful for finding relevant information
3.1.2 Web Application
- A computer program that offers a service or performs tasks via a browser
- It interacts with a server remotely
- Examples include CRM systems, handling tasks like customer relations, management, supplies etc
- Back-end can involve multiple or a single server
3.1.3 Website Development
- A website shares information and content
- Viewers cannot edit or change anything
3.1.4 Static Website
- Static websites display the same content to all viewers
- Content does not change unless the website owner makes the changes
3.1.5 Dynamic Website
- Dynamic information changes and adjusts based on the user input
- Examples are changing background colors based on user clicks
3.2 HTML
- Hypertext Markup Language used to define and display webpage contents
- Uses tags to define and display content
- Elements are identified by start and end tags
3.2.2 Tags - in HTML
- HTML is a tag based programming language
- HTML tags are quite self explanatory
- Every object on a webpage is characterized by a tag
3.2.2.1 HTML Tag
- Every html document is identified by and tags
- Anything written between these tags is a html document
3.2.2.2 Head Tag
- Encloses tags that are not part of the main body
- Holds metadata about the webpage, such as the title
3.2.2.3 Title Tag
- Gives the webpage a name
- Helps identify the webpage from others open on the browser
3.2.2.4 Body Tag
- The main part of the html document
- Encloses all contents of the document
3.2.2.5 Tags for Headings
- Six different levels of headings in HTML
- Level 1 heading is the largest, and level 6 is the smallest
3.2.2.6 Tag for Line Break
- Use to create a line break between two different sentences
- HTML does not recognize new lines
3.2.2.7 Span Tag
- Provides style and arrangement to a line
- Div tags organize an entire section of the page
- Emphasizing, italics, bold, and strong tags
3.2.2.8 Bullets & Numbering
- HTML provides unordered(
- ) and ordered(
- ) list
- Can use decimals or letters
3.2.3 Manipulating Data with Tables
- Using table tags to allocate and display data
- Header row uses
tags - Data is displayed using
tags 3.2.4 Links to Resources
- Links (hyperlinks) allow redirection to other pages or documents
- Defined by tag-pair
- 'Href' attribute specifies location and destination, while 'target' is optional
- Used for text or images
3.3 Cascading Style Sheets (CSS)
- Provides presentation and arrangement for webpage components
- CSS handle appearance, and presentation
- Three ways to apply CSS
- Inline: CSS attributes are added within the HTML
- Embedded: CSS styles are defined in the webpage header
- External: Separate CSS file linked to the HTML
3.3.2 Homepage Decor
- Style tag-pairs in the body define the appearance of headings and body
- 'Alt' attribute describes a picture on a webpage
3.4 JavaScript
- A language used to make webpages dynamic
- Javascript code embeds the starting and ending <script> tags
3.4.1 Let's Meet Javascript
- Javascript code can be inside <script> < /script> tags
- Javascript code can output to a document using "document.write()" function
3.4.2 Variables
- A variable is used to store a value for future use
- Variables can be assigned data (numeric, characters/strings or Boolean)
- Variables are case sensitive and are identified by their name
- JavaScript uses "var" as a keyword to declare variables
3.4.3 Operators
- Addition (+), Subtraction (-), Multiplication (*), Division (/), Modulus (%)
- Operators are used to perform mathematical operations in JavaScript
3.4.4 Conditional Statement
- Conditional statements control the execution of sections of code based on specific conditions
- If condition is true, the block of code will execute otherwise skipped
- JavaScript uses comparison operators to check conditions
3.4.5 Iterative Statement- For loop
- Repetition of blocks of code several times
- Initialized with start index, an end condition, and a way for the index to increase or decrease between each loop
3.4.6 Nested Loops
- Multiple loops used in one block of code
- A sequence of instructions where one loop is wrapped in another to create desired results

- A data type that can hold multiple homogeneous data elements
- Access individual elements using their index from zero
3.4.8 Functions
- A set of instructions that create a specific action
- Can use parameters/arguments to pass data to the function
3.5 Debug The Code
- Debugging helps to find and fix errors in code
- Breakpoints help in tracking code execution and identifying variables
3.6 Creating a Dynamic Website
- Website content that changes and adjusts based on user input
- JavaScript used in conjunction with HTML and CSS for dynamic websites
- Function used to control the ordering and content of webpage's output
Unit 4 Data and Analysis
- Explains scope of data science
- Data types, data collection, and data storage methods
- Big data, and applications
4.1 Data and Analysis
- Data is a collection of information
- Data analysis is a process of examining and studying data to provide insights
- Data analysis use tools such as charts and graphs
4.2.1 Data types in Data Science
- Categorical/Qualitative data.
- Nominal (unordered categories like color)
- Ordinal (ordered categories like grades)
- Quantitative/Numerical data.
- Continuous (can be divided infinitely like height)
- Discrete (finite values like number of students)
