This package provides an ES2015 Object.assign() ponyfill, so you can use Object.assign-style copying of enumerable own properties in environments that do not support it. It is useful for merging objects in JavaScript, including overwriting equal keys and ignoring null or undefined sources.

Recent updates
v4.1.1
Release notes for v4.1.1 were not provided by the publisher. The code diff shows this is primarily a tooling and test-suite refresh (switching test runner to AVA, CI Node version bump, minor README updates) with only small internal tweaks in the runtime implementation.
v4.1.0
Release 4.1.0 primarily updates the ponyfill to detect buggy V8 implementations that have incorrect property enumeration order, and to avoid using the native Object.assign on those runtimes. It also adds a test specifically covering the buggy V8 enumeration behavior.
v4.0.1
Release v4.0.1 is tagged but the publisher provided no release notes. There is insufficient information to identify specific new features, fixes, or breaking changes from the release documentation alone.
v4.0.0
Version 4.0.0 focuses on improving the behavior and performance of object-assign. The release makes assignment faster and preserves the order of properties during assignment.
