+/**
+* Assigns properties from multiple source objects to a target object.
+*
+* This function merges the properties of the source objects into the target object,
+* including properties from the prototype chain. If a property in the source objects
+* is equal to the corresponding property in the target object, it will not be overwritten.
+*
+* @param {any} object - The target object to which properties will be assigned.
+* @param {...any[]} sources - The source objects whose properties will be assigned to the target object.
+* @returns {any} The updated target object with properties from the source objects assigned.
+*
+* @example
+* const target = { a: 1 };
+* const result = assignIn(target, { b: 2 }, { c: 3 });
+* console.log(result); // Output: { a: 1, b: 2, c: 3 }
