Computer Programming: JavaScript, Python, HTML, SQL, CSS

JavaScript is extremely versatile making it an excellent place for the beginner programmer to start. Start small with perhaps an image gallery or programming a response to a button click, and then as your experience expands you'll be able to create more complex, detailed projects as well as perhaps some database driven apps if you so desire. The sky is the limit, well that and your desire to learn. If you start small and consistently move forward you will get there. Let's start with something simple. A commonly used first example in many programming languages is the hello world example. Hence let's do that one here. It is in a few simple steps. A common place to begin is to create a folder and typically I would give it the name script without the quotations. Then open that folder and create another new file. I will strive to provide more than enough to get you started. Future chapters will delve deeper into some of the things you can do. Let's start with what CSS means. CSS is short for Cascading Style Sheets. Basically CSS was designed to supply an efficient method of styling and presenting HTML. HTML is the content or meaning of a document, whereas CSS gives you a way to add a cool factor to the presentation of that document. Styles are a great addition to HTML, yet they retain their own distinct format of property to value. Chapter 4. The Essentials for SQL For your introduction to SQL, I thought starting with the simple SELECT queries would be a good place to begin. So let's dive in and get started. Hopefully you will learn how tables in an SQL server database are identified. It is also imperative for you to grasp a full understanding of how to listen to a table's columns. Another important aspect is to develop the ability to use the SQL SELECT statement for various operations, as well as learning some tested and true techniques for debugging your commands, thus saving you time and fixing mistakes. There are two parts to a SELECT statement. The first part is a description of the specific columns needed to view, These could range from failing to utilize adopted conventions, or if the wrong function is called, if a variable is not initialized, or even if you use the wrong variable name in the wrong place. Users can sometimes spot the design flaws, while at other times the flaws are not visible to the user and make fixing or improving a program significantly more difficult. Most obvious flaws are spotted when a program encounters the limits of the computer it is running on, such as a lack of processor speed, availability of memory or disk space, or even overwhelming input or output devices. Sometimes the problem may lie not with the software or program, but rather with the hardware or computer that the program was running on. This can cause some extreme difficulty in identifying the problem, especially if the person attempting to debug the problem doesn't have access to the computer it was being run on. There is no typical performance when the hardware fails, except that it will typically be in a widely unexpected manner. You should keep in mind that no matter how well written your code is, if it is not the correct code, it still won't help anyone. Also, if you have the best written code, and it is the appropriate code, but if the user interface is too difficult for the user to produce the desired results, it's not much better than having written no code or the wrong code. Sometimes it is helpful to remember that the typical user does not think in terms of algorithms, web pages, or command line interfaces as a developer or programmer is apt to do. It can prove particularly helpful to take the time to talk with your user and understand what it is they think the program should be doing that it's not. It is not uncommon for the user to expect things of a program that it is not capable of doing. It is impossible to fix a bug that doesn't exist.
