Improved deep equality testing for Node.js and the browser.

Fast deep equal

node's assert.deepEqual algorithm

Like lodash isEqualWith but for shallow equal.

Does a shallow comparison of two objects, returning false if the keys or values differ.

Map key-value pairs treating deeply-equal keys as equivalent objects

node's assert.deepEqual algorithm except for NaN being equal to NaN

Sort an object's keys, including an optional key list

Constant-time comparison of Buffers

return whether two buffers are equal

Fastest deep equal comparison for React. Great for React.memo & shouldComponentUpdate. Also really fast general-purpose deep comparison.

Tiny deep equal comparator

Compare DNS record strings for equality

Check if two arrays are equal

JSON diff

chai plugin to match objects and arrays deep equality with arrays (including nested ones) being in any order

An Object.keys replacement, in case Object.keys is not available. From https://github.com/es-shims/es5-shim

Typescript-compatible minimalistic shallow equality check for arrays/objects

Robustly get an object's own property keys (strings and symbols), including non-enumerables when possible
