Are you struggling with changing only the parent object in JavaScript without affecting its children objects? It can be tricky, but with the right approach, you can achieve it. Here's how you can do it:
1. Use Object.assign() method:
The Object.assign() method is used to copy the values of all enumerable own properties from one or more source objects to a target object. It can be used to change only the parent object without modifying its children objects. Here's an example:
```javascript
let parentObject = { name: 'John', age: 30 };
let childObject = { hobby: 'Reading' };
let modifiedParentObject = Object.assign({}, parentObject, { age: 25 });
console.log(modifiedParentObject); // Output: { name: 'John', age: 25 }
```
2. Use spread operator (...) :
The spread operator (...) is another way to change only the parent object without affecting its children objects. It allows you to create a shallow copy of an object and modify its properties. Here's an example:
```javascript
let parentObject = { name: 'John', age: 30 };
let childObject = { hobby: 'Reading' };
let modifiedParentObject = { ...parentObject, age: 25 };
console.log(modifiedParentObject); // Output: { name: 'John', age: 25 }
```
3. Use JSON.parse() and JSON.stringify() methods:
If you want to change only the parent object in a nested object structure, you can use JSON.parse() and JSON.stringify() methods to achieve it. Here's an example:
```javascript
let nestedObject = {
parent: {
name: 'John',
age: 30
},
child: {
hobby: 'Reading'
}
};
let modifiedNestedObject = JSON.parse(JSON.stringify(nestedObject));
modifiedNestedObject.parent.age = 25;
console.log(modifiedNestedObject); // Output: { parent: { name: 'John', age: 25 }, child: { hobby: 'Reading' } }
```
By using these methods, you can change only the parent object in JavaScript without affecting its children objects. It's important to carefully choose the method that best fits your specific use case and object structure.
