- 2. What Is Coding • Code is language that allows humans to communicate and interact with computers. • There are three basic goals of coding 1. Functionality 2. Reusability 3. “Good” Style
- 3. Continuation • Essentially, code needs to be useful as well as efficient, and clean.
- 4. How Is Code Developed? Code is usually written and tested in an IDE. • An IDE (acronym) is an Integrated Development Environment • It is where a programmer creates and “runs” code to test if it works properly. • Often, much experimentation is needed to work out the bugs in one’s code.
- 5. IDE • IDEs are extremely important. • For this course, we recommend a free multi- platform IDE called NetBeans. • Remember to always test your code after an edit so that you can identify problems immediately.
- 6. Basics of Web Dev • Websites are created with a combination of several programming languages, including: – HTML – CSS – Javascript/JQuery/Angular JS – PHP / SQL
- 7. Fundamental Web Dev Languages • HTML stands for Hypertext Markup Language • CSS stands for Cascading Style Sheet • Together, HTML and CSS designs the basic layouts, interfaces, and displays of web pages. • Javascript allows for the creation of responsive websites. • While HTML and CSS “paint” and “draw” a webpage, Javascript “animates” them. • Angular JS is a javascript framework that is ued to create mobile web apps.
- 8. More Advanced Languages • PHP stands for Hypertext Preprocessor. • Often, it works together with SQL (Structured Query Language) to access and communicate with databases. • They are useful when creating account systems on websites.
- 9. Categorization of Web Languages • There exist two types of web languages: client side languages (HTML, CSS, Javascript), and server side languages (PHP). Languages such as C#, C++ and Java are sometimes used as server side languages as well
- 10. Explanation • The Server is responsible for serving pages. The Client requests pages from the Server, and displays them to the user. In most cases, the client is a web browser. • The User uses the Client in order to surf the web, fill in forms, watch videos online, etc.
- 11. Course Outline • You don’t need to learn all those languages in order to create your own website. • If you want to create a basic website like a blog, all you need is HTML and CSS
