A very good W3school tutorial can be found here.

Javascript – changing an object key's values

How can I change the **obj2 **values instead of doing it one by one as shown is there a way that doing it at once ?

const obj1={
  name:`serag`,
  age:30,
  children:
  {
    daughter:`leila`,
    son:`seif`
  }
};

const obj2 = JSON.parse(JSON.stringify(obj1));

let {name,age,children}=obj2;
// obj2.name =`omar`;
// obj2.age=30;
// obj2.children.daughter=`huda`;
// obj2.children.son=`ahmed`;

I just started to learn JS consider myself a beginner

    One of the many ways is to use spread operator.

    const obj3 = {...obj1}

    You can also use Object.assing() for shallow copy.

    const shallowCopy = Object.assign({}, obj1);

    For more information please have a look at this.

    Hope, this helps.

    You can use object assign to clone and modify the object at once.

    // obj1 
const obj2 = Object.assign({}, obj1, {
  name: "omar",
  age: 35,
  children: Object.assign({}, obj1.children, {
    daughter: "huda",
    son: "ahmed",
  }),
});
