Difference Packages

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

Measure the difference between two strings using the Levenshtein distance algorithm

Get the diff type of two semver versions: 0.0.1 0.0.2 → patch

Create an array with values that are present in the first input array but not additional ones

The lodash method `_.difference` exported as a module.

Fastest Levenshtein distance implementation in JS.

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

The most efficient JS implementation calculating the Levenshtein distance, i.e. the difference between two strings.

Javascript utility for calculating deep difference, capturing changes, and applying changes across objects; for nodejs and the browser.

Finds degree of similarity between strings, based on Dice's Coefficient, which is mostly better than Levenshtein distance.

Get a pretty output of the original, minified, gzipped size of a string or buffer: 130 B → 91 B → 53 B (gzip)

Exact subtraction of non-increasing overlapping sequences

Boolean operations on polygons (union, intersection, difference, xor)

Finds the gradient of an ndarray using finite differences

Update object by mapping diff properties

Apply boolean Polygon clipping operations (intersection, union, difference, xor) to your Polygons & MultiPolygons.

a library for matching human-quality input to a list of potential matches using the Levenshtein distance algorithm
