👉 The `document.createTextNode("Light Particles")` line in JavaScript creates a new text node with the string "Light Particles" attached to it, which serves as a label or title for the text that will follow. This text node is part of a larger document structure, likely used in a web page or a document editor, where it provides context or a description for a section containing light particles. Light particles, often visualized as small, glowing dots or trails, are typically used to simulate effects like smoke, fire, or atmospheric phenomena. This text node can be styled and positioned within the document using other methods, such as `appendChild`, `setAttribute`, or CSS, to enhance the visual representation of these particles in a dynamic and interactive way.
