Fast Diff 
This is a simplified import of the excellent diff-match-patch library by Neil Fraser into the Node.js environment. The match and patch parts are removed, as well as all the extra diff options. What remains is incredibly fast diffing between two strings.
The diff function is an implementation of "An O(ND) Difference Algorithm and its Variations" (Myers, 1986) with the suggested divide and conquer strategy along with several optimizations Neil added.
1var diff = require('fast-diff'); 2 3var good = 'Good dog'; 4var bad = 'Bad dog'; 5 6var result = diff(good, bad); 7// [[-1, "Goo"], [1, "Ba"], [0, "d dog"]] 8 9// Respect suggested edit location (cursor position), added in v1.1 10diff('aaa', 'aaaa', 1) 11// [[0, "a"], [1, "a"], [0, "aa"]] 12 13// For convenience 14diff.INSERT === 1; 15diff.EQUAL === 0; 16diff.DELETE === -1;
