An introductory reading that defines the stack data structure, explains its restricted top-only access model, and establishes foundational vocabulary such as push and pop for learners encountering stacks for the first time.

Module Content
15 items of 4 types: Topic Detail, Topic Videos, Readings, Activities and Games. Your instructor made most of them with CourseBuilder+, a program that uses AI to draft course material; each type says how its items were made.
Topic Detail (6)
A detailed reading for each topic, covering its subtopics in order with explanations and examples — reading only, no videos (for the reading with videos, see Topic Detail with Video). Drafted with AI from the module's topics, subtopics and learning outcomes.
-
-
A focused reading that explains the Last-In, First-Out (LIFO) principle in depth, clarifying how this governing rule shapes stack behavior and distinguishes stacks from other data structures.
-
A reading that covers the internal mechanics of stack implementation, including how memory is organized, how elements are tracked, and the trade-offs between array-based and linked-list-based approaches, giving learners a under-the-hood understanding of the structure.
-
A hands-on reading and coding guide that walks learners through implementing a stack class in JavaScript, demonstrating push, pop, and related operations with a practical, language-specific example.
-
A reading that explains how stacks are used to evaluate mathematical expressions and handle nested parentheses, walking learners through the algorithmic process of using stacks to parse and resolve expressions correctly.
-
A reading that explores practical, everyday applications of stacks — including undo functionality in text editors and browser navigation history — helping learners connect the abstract LIFO concept to real software they already use.
Topic Videos (7)
Videos for each topic: a short introduction to the topic, then up to three YouTube videos embedded, each with what it covers and why it is worth watching. The videos were found by an AI search of YouTube (well viewed, with captions where possible), and the page was written with AI.
-
An introductory reading that defines the stack as a restricted container where items are added and removed only at the top, explaining how this single constraint produces Last-In, First-Out ordering and why stacks matter in computer science; learners read it first to establish core vocabulary before studying operations in detail.
-
A focused lesson on the Last-In, First-Out rule, showing why only the most recently added element can be removed or inspected and how this deliberate restriction defines the stack's usefulness; learners use it to build intuition for predicting stack behavior in traced examples.
-
An explanation of how a stack works internally, covering array and linked-list backing storage and the role of the 'top' marker in defining push, pop, and peek, along with the cost of each operation; instructors use it to connect abstract stack behavior to concrete memory and performance considerations.
-
A hands-on coding lesson in which learners write a Stack class from scratch in JavaScript, implementing the constructor with array-based storage plus push, pop, and peek methods; used as a practical exercise to turn the conceptual stack into working code.
-
An applied lesson on using stacks to evaluate arithmetic expressions, addressing operator precedence, parentheses, and associativity through stack-based parsing and conversion techniques; learners work through examples like 3 + 4 * (2 - 1) to see the algorithm in action.
-
A real-world applications reading that connects push/pop/peek and LIFO ordering to everyday software features such as Ctrl+Z undo history, browser back navigation, and call stacks; learners use it to recognize when a stack is the right structure for a design problem.
-
A consolidated module overview page that compiles all topics in the unit — stack fundamentals, the LIFO principle, internal implementation, building a stack in JavaScript, expression evaluation, and real-world use cases — into one continuous document for review or offline reading.
Readings (1)
Reading for this module: drafted with AI from the module's topics, or brought in from the course's own files.
-
A reading that explores practical, everyday applications of stacks — including undo functionality in text editors and browser navigation history — helping learners connect the abstract LIFO concept to real software they already use.
Activities and Games (1)
Interactive activities and games that run in the browser — practice by doing. Drafted with AI from the module's topics.
-
A fill-in-the-blank reading activity covering key terminology and concepts of the stack data structure, where learners type missing terms into a passage and receive instant right/wrong feedback to reinforce their understanding of stack vocabulary and principles.
