Client-Side Text Transformation Flow
How string manipulation executes directly inside your browser:
// 1. Ingest raw text stream
const textStream = document.getElementById("text-editor").value;
// 2. Perform in-memory text parsing & regex sanitization
const formattedText = transformString(textStream, {
stripTags: true,
preserveWhitespace: false,
memoryBounded: true
});
// 3. Render clean output with zero server uploads
