Yes, recent versions of Node.js (v15.0.0 and above) include built-in capabilities to compare two strings and show their differences using the native assert module. When you use assert.strictEqual() to compare two strings and they don't match, Node.js throws an AssertionError that includes a diff-style message showing the differences between the two strings. This is especially helpful for debugging or testing, as it clearly highlights what changed. While this method is not intended specifically for generating diffs outside of testing contexts, it can be used creatively to display string differences without relying on third-party libraries. However, for more advanced or custom diff outputs-such as word-by-word or character-by-character comparison-you may still need to write a custom function or use libraries like diff for more control. Still, Node.js does offer a basic native way to view differences between strings via assertion errors.
