Here is the microdiff benchmark wrapped in benchmark.js: https://github.com/stephank/js-diff-benchmarks

I added three more libraries, and also the size in bytes of `JSON.stringify(result)` for each. (That was also important for me in making symmetry.)

The results from benchmark.js are a lot more consistent on my laptop:

Benchmark: Small object (baseline)

- @n1ru4l/json-patch-plus x 1,426,241 ops/sec ±0.29% (94 runs sampled) (94 bytes)

- deep-diff x 337,122 ops/sec ±0.45% (95 runs sampled) (193 bytes)

- deep-object-diff x 2,138,118 ops/sec ±0.25% (96 runs sampled) (60 bytes)

- diff x 59,277 ops/sec ±0.60% (97 runs sampled) (268 bytes)

- jsondiffpatch x 841,880 ops/sec ±0.38% (96 runs sampled) (113 bytes)

- microdiff x 6,979,471 ops/sec ±0.77% (95 runs sampled) (171 bytes)

- symmetry x 8,666,619 ops/sec ±0.21% (97 runs sampled) (7 bytes)

Benchmark: Large Object (300 properties)

- @n1ru4l/json-patch-plus x 16,902 ops/sec ±0.66% (92 runs sampled) (515 bytes)

- deep-diff x 8,378 ops/sec ±0.68% (96 runs sampled) (1194 bytes)

- deep-object-diff x 19,647 ops/sec ±0.40% (94 runs sampled) (410 bytes)

- diff x 737 ops/sec ±0.45% (94 runs sampled) (12051 bytes)

- jsondiffpatch x 14,306 ops/sec ±0.76% (95 runs sampled) (714 bytes)

- microdiff x 22,131 ops/sec ±0.25% (95 runs sampled) (935 bytes)

- symmetry x 21,432 ops/sec ±0.92% (98 runs sampled) (424 bytes)
