A <a href="../terms/first-class-function.md" class="link-internal">first-class function</a> is a function that a language treats like any other value — it can be stored in a variable, passed as an argument, and returned as a result.</p> <pre tabindex="0"><code>double = λx. x * 2 </code></pre><p>Here <code>double</code> is a variable whose value is a function. It is not a declaration — it is an assignment of a function value to a name, no different in kind from assigning a number to a name. This is the starting point for everything that follows.</p> https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/texts/debugging-basics/ Thu, 01 Jan 2026 00:00:00 +0000 https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/texts/debugging-basics/ <p>Audience: beginners learning how to fix programs.</p> <p>Learning goal: explain a simple debugging workflow.</p> <p>Debugging starts by reproducing an error, isolating the cause, and verifying a fix. Logging or print statements help trace program flow.</p> <p>Check for understanding: Why is reproducing an error the first step?</p> https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/domains/functional/texts/functional-overview/ Thu, 01 Jan 2026 00:00:00 +0000 https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/domains/functional/texts/functional-overview/ <p>Audience: beginners learning programming paradigms.</p> <p>Learning goal: describe pure functions and immutability.</p> <p>Functional programming treats computation as evaluating expressions and composing pure functions. Immutability helps reduce unintended side effects.</p> <p>Check for understanding: Why are pure functions easier to reason about?</p> https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/texts/modularity/ Thu, 01 Jan 2026 00:00:00 +0000 https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/texts/modularity/ <p>Audience: beginners learning to organize code.</p> <p>Learning goal: explain why programs are split into modules and functions.</p> <p>Modularity separates code into reusable parts. Functions and modules keep responsibilities clear and reduce duplication.</p> <p>Check for understanding: How does modularity make programs easier to maintain?</p> https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/domains/object-oriented/texts/oop-overview/ Thu, 01 Jan 2026 00:00:00 +0000 https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/domains/object-oriented/texts/oop-overview/ <p>Audience: beginners learning about programming styles.</p> <p>Learning goal: explain how objects and classes organize code.</p> <p>Object-oriented programming models a system as objects with state and behavior. Classes define shared structure, while objects carry specific data.</p> <p>Check for understanding: What is the difference between a class and an object?</p> https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/domains/paradigms/texts/paradigms-overview/ Thu, 01 Jan 2026 00:00:00 +0000 https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/domains/paradigms/texts/paradigms-overview/ <p>Audience: beginners comparing programming styles.</p> <p>Learning goal: list common paradigms and what they emphasize.</p> <p>Imperative paradigms focus on commands and state. Declarative paradigms focus on describing results. Event-driven, logic, and dataflow paradigms structure how programs react to events or express constraints.</p> <p>Check for understanding: Which paradigm focuses on expressing rules instead of explicit steps?</p> https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/texts/programming-overview/ Thu, 01 Jan 2026 00:00:00 +0000 https://emsenn.net/library/domains/engineering/domains/tech/domains/computing/domains/software/domains/programming/texts/programming-overview/ <p>Audience: beginners who want to understand what programming is.</p> <p>Learning goal: explain programming as specifying behavior in steps.</p> <p>Programming describes how a machine should handle inputs, make decisions, and produce outputs. Programs can be short scripts or large systems.</p> <p>Check for understanding: What does it mean for a program to specify behavior?</p>
