+/// ## Updating Text Content Using a Diff Algorithm
+///
+/// A common requirement is to update the current text to a target text.
+/// You can implement this using a text diff algorithm of your choice.
+/// Below is a sample you can directly copy into your code, which uses the
+/// [fast-diff](https://www.npmjs.com/package/fast-diff) package.
+///
+/// ```ts
+/// import { diff } from "fast-diff";
+/// import { LoroText } from "loro-crdt";
+///
+/// function updateText(text: LoroText, newText: string) {
+///   const src = text.toString();
+///   const delta = diff(src, newText);
+///   let index = 0;
+///   for (const [op, text] of delta) {
+///     if (op === 0) {
+///     index += text.length;
+///   } else if (op === 1) {
+///     text.insert(index, text);
+///     index += text.length;
+///   } else {
+///     text.delete(index, text.length);
+///   }
+/// }
+/// ```
