Pre-Programming: Everything you need to know before you code

Explore how the internet works, including TCP/IP, DNS, and HTTP, and how the World Wide Web standardizes information for developers.

Learn how the internet works by exploring roles of clients, servers, and nodes, and how an internet service provider, modem, and router connect your device to a server over wifi.

Explore how browsers act as interpreters that connect to servers and translate web code into system actions, and compare Chrome, Firefox, Safari, Opera, and IE.

Explore the anatomy of mobile sites and mobile apps. Understand how responsive web design adapts pages for small screens and how apps bundle files offline.

Learn how programming languages are rules that tell computers what to do, since machines understand machine code, not human language, and why there are multiple languages for different use cases.

Explore how JavaScript drives interactivity on web pages—from dynamic loading, font changes, and popups to animations—note its 1990s origins and future focus on full-stack JavaScript.

Discover back-end languages that run on servers to service websites and web apps, tackle backend complexity, and learn how software engineers bridge front-end and back-end work, with Python coming up.

Discover PHP, an open-source back-end language with a large, free community and easy-to-learn appeal, powering Facebook and WordPress despite occasional inefficiencies.

Explore Ruby, a fast, easy-to-use back-end language designed to save development time with automation and intuitive changes, while noting its newness, trendy appeal, and performance limits on large systems.

Explore how to use Sublime Text as a beginner-friendly text editor and IDE, save HTML files, color-code code, and preview changes in the browser for quick feedback.

Explore how programming languages share core concepts while using different syntax, with comparisons of python, php, and java and an explanation of strict versus expressive syntax.

Learn how variables store information, assign values like A=1 and B=2, and compute subtotals, tips, and totals. See how variables prevent hardcoding and propagate across pages in apps.

Learn how printing outputs back-end calculations to the browser, with Python, Ruby, and PHP examples, and distinguish front-end display from back-end logic.

Master the practice of commenting to explain code, prevent browser misreadings, and ease future hires when maintaining or extending an existing codebase.

Learn how strings store text in variables and display content with print. Master handling quotes with escape commands, cross-language differences in quotation marks, and concatenation in Python and PHP.

Learn how arrays store a series of like-formatted data in one container, saving time by avoiding multiple variables, and how to access items with a pointer.

Explore how programming frameworks provide a predefined structure that speeds development by reusing code and automating common tasks across languages like PHP, Python, and Ruby.

Front-end frameworks provide pre-made systems, including grid layouts, UI kits, and interaction snippets, to speed up styling and interactivity with ready-to-use components and routines.

Discover how back-end frameworks organize server-side code, offer pre-made functions for databases, APIs, and payments, and compare full versus micro frameworks while shaping programming styles like MVC and OOP.

Differentiate the development environment from the integrated development environment (IDE), noting how IDEs support frameworks, syntax checks, auto-complete, file organization, and version control, with examples like Visual Studio and Xcode.

Learn what a content management system (CMS) is and why it matters for web publishing. See how CMSs enable non-programmatic content management with templates and analytics.

Explore git as an online repository for saving code versions, its distributed, cloud-based design, and how GitHub features like bug tracking and forking enable collaborative development.

Explore continuous integration as a system that speeds up large-team development through frequent check-ins, automated builds, and coordination via version control and build servers.

Explore full stack JavaScript, using Node.js and the V8 engine to run on front-end and back-end, with asynchronous JavaScript and multi-threading; consider its efficiency and database limitations.

Explore how to learn programming, including languages, tracks, and online resources, and maximize ROI on your time and money. Clarify web development, software development, full stack development, and hackers.

Define web development, software engineering, full stack development, and hackers, and explain their front-end and back-end focuses, differences between websites and apps, and typical roles.

Choose your programming path by weighing design versus logic, front-end versus back-end. Consider startup or big company goals and solo projects, and pick Python or Ruby to get things done.

Learn front-end development by mastering HTML, CSS, and JavaScript, enjoy rapid visual feedback through interactive design, and follow a practical path from basics to frameworks with online courses and bootcamps.

Learn Ruby, PHP, and Python for back-end development, starting with syntax basics. Utilize Codecademy and Codewars, plus Google and Coursera courses, to master Rails and Django.

Stick with technologies that persist over time instead of chasing hype around mean stack, MongoDB, Node.js, or React. For freelancers, prioritize clear client communication and core skills over flashy tech.
