🎯 Obiettivi didattici

  1. Definire cosa sia un programma e spiegare i diversi livelli di astrazione nei linguaggi informatici.
  2. Utilizzare numeri e operatori aritmetici di JavaScript per produrre valori.
  3. Dichiarare e aggiornare variabili rispettando le convenzioni di denominazione e i limiti sulle parole riservate.
  4. Implementare un controllo del flusso robusto usando cicli do, for e istruzioni switch, mantenendo il codice pulito grazie all'indentazione e ai commenti.
  5. Definire e invocare funzioni utilizzando diverse notazioni, gestendo parametri, argomenti opzionali e scope lessicali annidati.
  6. Applicare concetti funzionali avanzati come ricorsione, chiusure e stack di chiamata per risolvere puzzle algoritmici complessi.
  7. Utilizzare metodi specializzati di oggetti e array per gestire strutture dati complesse e stringhe.
  8. Implementare funzioni di ordine superiore (filter, map, reduce) per astrarre logiche e comporre trasformazioni sui dati.
  9. Navigare e manipolare la catena dei prototipi per creare istanze di oggetti strutturate e riutilizzabili e interfacce polimorfiche.
  10. Implementare interfacce polimorfiche per gestire visualizzazioni dati complesse (tabelle).

Lezioni

Lesson

1 Lesson 1

This lesson introduces the concept of programming as the art of subduing complexity by creating immaterial logic that directs physical hardware. Students will learn the fundamental structure of JavaScript, including the roles of variables, control flow, and the distinction between statements and expressions.

2 Lesson 2

This lesson explores advanced control flow in JavaScript, focusing on sophisticated iteration patterns like for loops, do-while loops, and multi-way branching with switch statements. Students will learn to manage program execution precisely using break and continue keywords, modular arithmetic, and nested loops to solve complex algorithmic challenges.

3 Lesson 3

This lesson explores the concept of abstraction in programming, focusing on how to transition from imperative, hardware-level logic to declarative, human-readable code. Students will learn to implement and refine flexible functions, such as range and sum, while analyzing the performance trade-offs associated with the abstraction tax.

4 Lesson 4

This lesson explores interface-based polymorphism by defining a standardized Table Interface that allows layout engines to process diverse data types through a consistent set of methods. Students will learn to implement flexible, decoupled systems by using defensive programming techniques and interface contracts to manage object rendering and alignment.

5 Lesson 5

This lesson introduces Regular Expressions (RegExp) in JavaScript, covering how to define patterns using literal notation or constructors and how to use the .test() method for validation. Students will learn to manage case sensitivity, handle special characters through escaping, and apply these techniques to dynamic string matching tasks.

6 Lesson 6

This lesson explores the evolution of JavaScript module systems, focusing on how to prevent namespace pollution through techniques like Immediately Invoked Function Expressions (IIFEs) and closures. Students will learn to design robust, encapsulated code by creating private scopes and structured public interfaces for their modules.

7 Lesson 7

AI020: Events and Interactive Platforms (Lesson 7) explores the technical foundations of building dynamic web experiences through DOM manipulation, regular expressions, and event handling. Students will learn to transform static content into interactive environments by implementing efficient workflows for real-time feedback and user input tracking.

8 Lesson 8

This lesson explores the performance advantages of the HTML5 Canvas API over SVG for high-density graphics by utilizing a 2D rendering context to bypass DOM overhead. Students will also examine the role of the transport layer in web applications, specifically analyzing the performance trade-offs between TCP and UDP for data transmission.

9 Lesson 9

This lesson explores the necessity of asynchronous programming in web development to prevent UI freezing caused by synchronous I/O operations. Students will learn to implement event-driven patterns and browser persistence APIs to maintain responsive, high-performance applications during network-intensive tasks.

10 Lesson 10

This lesson explores advanced Canvas API techniques for building interactive drawing tools, focusing on state management, composite operations, and mathematical constraints. Students will learn to implement dynamic features like spray brushes and erasers by manipulating canvas context properties and handling mouse events through higher-order patterns.
