<script type="text/javascript" src="diff.min.js"></script> <script type="text/javascript"> var _ = window.diff, compare = _.compare, merge = _.merge, compareStr = _.compareStr, mergeStr = _.mergeStr; </script>
Compare
var seq1 = [1, 2, 'a', 'b'],
seq2 = [1, 2, 'c', 'b'];
var seqResult = compare(seq1, seq2); // seqResult: [[2, 1, ['c']]
var s1 = 'abc',
s2 = 'abcd',
splitter = '';
var strResult = compareStr(s1, s2, splitter); // strResult: { splitter: '', diff: [[3, 0, 'd']] }
Merge
var seq3 = merge(seq1, seqResult); // seq3: [1, 2, 'b']
var s3 = mergeStr(s1, strResult); // s3: 'abcd'
