JavaScript Object Iterations

// Copies properties from a source object to a target object
Object.assign(target, source)

// Create Target Object const person1 = { firstName: "John", lastName: "Doe", age: 50, eyeColor: "blue" };

// Create Source Object const person2 = {firstName: "Anne",lastName: "Smith"};

// Assign Source to Target Object.assign(person1, person2);

The Object.groupBy() metodi obyekt elementlarini callback funksiyadan qaytgan string qiymatlarga ko'ra guruhlaydi
