Are you looking to modify the properties and values of the parent object in JavaScript without affecting its child objects? Here's how you can do it!
One way to change the parent object in JavaScript is by using the Object.assign() method. This method creates a new object by copying the values from the source objects to the target object. It does not modify the source objects. Here's an example:
```javascript
let parentObject = { name: 'John', age: 30 };
let newValues = { age: 35 };
let modifiedObject = Object.assign({}, parentObject, newValues);
console.log(modifiedObject);
// Output: { name: 'John', age: 35 }
```
In this example, we created a new object called modifiedObject by using Object.assign(). We passed an empty object as the target object, followed by the parentObject and newValues as the source objects. The method merged the properties from both source objects into the target object, and it returned the modifiedObject with the updated age.
Another way to change the parent object is by using the spread operator (...) in ES6. It allows you to expand the properties of an object into another object. Here's an example:
```javascript
let parentObject = { name: 'John', age: 30 };
let newValues = { age: 35 };
let modifiedObject = { ...parentObject, ...newValues };
console.log(modifiedObject);
// Output: { name: 'John', age: 35 }
```
In this example, we used the spread operator to expand the properties of both parentObject and newValues into a new object called modifiedObject. The result is similar to using Object.assign(), as it merged the properties and returned the updated age.
It's important to note that these methods only change the parent object and leave the original objects unchanged. This is particularly useful when you want to update the properties of an existing object without altering its original values or affecting its child objects.
By using Object.assign() or the spread operator, you can efficiently change the parent object in JavaScript without worrying about modifying the source objects. These methods provide a clean and concise way to update the properties and values of the parent object while keeping the original data intact.
