object-assign is a widely-used, minimal polyfill for the ECMAScript 6 Object.assign() method. This function copies the values of all enumerable own properties from one or more source objects to a target object. It returns the target object, modifying it directly. object-assign is essential for environments lacking native ES6 support, ensuring consistent object property merging across different JavaScript runtimes and browsers. Its small size and focused functionality make it a popular dependency in countless packages, enhancing JavaScript compatibility.
