      Introduction to Programming

      Welcome to the exciting world of programming! Let's start with a brief overview of programming and how it has evolved over the years.

      Programming is the act of creating instructions for a computer to follow. These instructions, also known as code, are written in a specific programming language (of which there are many). For instance, think of it like giving step-by-step instructions on how to make a PB&J sandwich. Just as one would detail the steps for spreading peanut butter on one slice of bread and jelly on another, programmers detail steps for the computer to perform tasks. These instructions are used to tell a computer to perform a wide variety of tasks, from simple calculations to complex software.

      The first programming language to be created was called Machine Language, developed in the 1940s. Machine Language was very basic, consisting only of a series of 0s and 1s that could be read and understood by a computer's processor. Since then, many other programming languages have been developed, each with unique features and capabilities. Some of the most popular programming languages today include Python, Java, C++, and JavaScript.

      Nowadays, you’ll interact with programming in almost every aspect of daily life, from the apps on your phone to the websites you visit to the cars you drive. Writing code is a field that is constantly evolving and offers endless opportunities for creativity and innovation.

      Learning to code will allow you to bring your ideas to life. Additionally, it’s a highly valuable skill to have in today's job market. Companies (and not just tech companies) are looking for talented programmers to help them build and maintain software applications, and the demand for these professionals is only expected to increase in the coming years. But perhaps the best thing about programming is that it's a skill that can be learned by anyone. All it takes is a bit of motivation, some time, and the right resources. So if you're ready to embark on this exciting journey, grab your computer and let's get coding! Oh, and one last thing – remember, the best way to learn programming is to have fun with it! Get creative and don't be afraid to experiment or make mistakes.

      Common Programming Languages & Uses

      There are many different programming languages to choose from. This chapter delves deeper into some of the most commonly used programming languages, while providing coding samples and detailed insights into their unique features and associated use cases.

      Python

      Python is a popular, high-level programming language celebrated for its readability and versatility. It is frequently chosen for web development, scientific computing, data analysis, and Artificial Intelligence. One of Python's standout features is its vast and active community of users. This community has contributed numerous libraries and frameworks that simplify the process of building intricate applications. Some renowned Python libraries include Django (a web framework), NumPy (a scientific computing library), and TensorFlow (a machine learning library).

      Sample Python Code:

      Java

      Java is a widely-used, object-oriented programming language. In the programming context, object-oriented refers to a design paradigm where data and functions are bundled into units called objects. Java's strength lies in its portability; Java code can execute on any device with a Java Virtual Machine (JVM) installed. This makes it the go-to choice for Android application and software development, as Android's primary supported language. Additionally, many large corporations depend on Java for their crucial business systems.

      Sample Java Code:

      C++

      C++ stands out as a high-performance, compiled language. For beginners, a compiled language means that the written code is transformed into machine code by a compiler before it's executed. C++ is a top pick for crafting extensive software systems like operating systems, web browsers, and games. Its efficiency allows programmers to write code that's close to the hardware level, meaning it can interact directly with system hardware, offering faster performance. C++ is also favored for high-performance applications, such as financial trading systems and simulations, due to its ability to process vast amounts of data swiftly.

      Sample C++ Code:

      JavaScript

      JavaScript is a dynamic programming language essential for crafting interactive web applications. It can alter a web page's content, layout, and behavior, and is commonly paired with HTML and CSS to produce visually captivating and adaptable websites. Beyond web development, JavaScript finds its use in mobile and desktop application development, courtesy of frameworks like Electron and Cordova. Additionally, server-side development often employs JavaScript, especially with libraries like Node.js.

      Sample JavaScript Code:

      There are many more languages than these four we’ve briefly overviewed, but this should give you a sense of the wide range and flexibility across different languages. You should eventually gain familiarity with all of the major languages to be able to work across all stacks of development.

      Introduction to Scripting

      Scripting is the act of writing small scripts, or programs, that can automate tasks. Scripting can help you automate tasks and streamline your workflows. These scripts can be written in a variety of languages, such as Python, Bash, or PowerShell, and are used to perform a wide range of tasks, from simple file management to
