JSON diff & patch (object and array diff, text diff, multiple output formats)

Implementation of paper 'An O(ND) Difference Algorithm and Its Variations' on array

Text and arbitrary-array diff and merge, fast, multiple algorithms

A JavaScript text diff implementation.

Display differences clearly so people can review changes confidently.

Find elements added and removed explicitly between two arrays or elements or objects.

Returns an array with only the unique values from the first array, by excluding all values from additional arrays using strict equality for comparisons.

Robust diff, match and patch algorithms to perform operations required for synchronizing plain text

Fast Javascript text diff

Compare items in two sequences to find a longest common subsequence

Generates a set of Sanity patches needed to change an item (usually a document) from one shape to another

Compare items in two sequences to find a longest common subsequence

Truncate a semver version: `1.2.3` → `1.2.0`

Small, fast, zero dependency deep object and array comparison

Find diff between any two variables where variables be any valid JavaScript data type like string, numeric, array or object

diff with unified diff format handling

A fast, minimal, memory-efficient diff algorithm on strings, arrays, and typed arrays.

Regular expression for matching semver versions

Deep diffs two objects, including nested structures of arrays and objects, and return the difference.
