node's assert.deepEqual algorithm
Type check values
compare two semver version strings, returning -1, 0, or 1
Fastest deep equal comparison for React. Great for React.memo & shouldComponentUpdate. Also really fast general-purpose deep comparison.
Damerau - Levenshtein distance by The Spanish Inquisition + relative distance
Measure the difference between two strings using the fastest JS implementation of the Levenshtein distance algorithm
node's assert.deepEqual algorithm except for NaN being equal to NaN
Get a compare function for array to sort
Compare DNS record strings for equality
safe, constant-time comparison of Buffers
Finds degree of similarity between strings, based on Dice's Coefficient, which is mostly better than Levenshtein distance.
Like lodash isEqualWith but for shallow equal.
Compare semver version strings to find greater, equal or lesser.
Securely compare two strings, copied from cryptiles
GraphicsMagick and ImageMagick for node.js
Compare strings containing a mix of letters and numbers in the way a human being would in sort order.
