This example demonstrates the foundational syntax and core concepts of JavaScript through a series of commented-out code snippets. It shows variable declarations, arithmetic operations, control flow with loops, and function definitions, including ES6 arrow functions. The visualization uses a simple SVG canvas with a script tag, and the code is written directly within an HTML file. It covers object literals and constructor functions, illustrating how to create and manipulate objects. The rendering is achieved through the SVG API, and the file includes no external libraries, relying solely on native JavaScript.
