The object.assign npm package had frequent releases in 2014 and 2015, with occasional updates in subsequent years. Releases became sparse after 2015, with a few versions in 2016, 2017, 2020, 2022, 2023 and 2024. There have been no releases so far in 2025.
object.assign is a widely used polyfill and utility for the ES2015 Object.assign() method. It copies the values of all enumerable own properties from one or more source objects to a target object. It's a crucial tool for older JavaScript environments lacking native Object.assign support, enabling developers to merge, clone, or extend objects consistently across different browsers and Node.js versions. It simplifies object manipulation and promotes code portability.
Object.assign npm package downloads show a general upward trend from March 2024 to August 2025, peaking in June and July 2025 around 240 million downloads. September 2025 downloads are significantly lower at 64 million, likely due to incomplete data for the current month.
