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

Recursively (deep) clone JavaScript native types, like Object, Array, RegExp, Date as well as primitives.

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

Deeply mix the properties of objects into the first object. Like merge-deep, but doesn't clone. No dependencies.

Take a nested Javascript object and flatten it, or unflatten an object with delimited keys

Returns true if a value exists, false if empty. Works with deeply nested values using object paths.

Recursively flatten an array or arrays.

return the first event in a set of ee/event pairs

An XML builder for node.js

Recursively merge values in a javascript object.

Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.

It's react's useEffect hook, except using deep comparison on the inputs, not reference equality
