diff-mark

A variant of Diffmark implemented in JavaScript.

Some important difference to the original C# version:

• Diff strings are strictly validated before marking.
• The derived diff strings are less ambiguous and more legible.

You can install it via npm install diff-mark, or just include the script diffmark.js in your web pages.
