Hey everyone, today I'm going to show you how to change only the parent object in JavaScript without affecting its children objects. Let's get started!
So, you have an object with nested objects, and you want to update the parent object without modifying its children. Here's how you can do it:
1. Use the spread operator: You can create a new object by spreading the parent object and then updating its properties. This will not affect the children objects. For example:
```javascript
const parentObj = {
name: 'John',
age: 30,
address: {
street: '123 Main St',
city: 'New York'
}
};
const updatedParentObj = {
...parentObj,
age: 35
};
```
2. Use Object.assign(): You can also use Object.assign() to update the parent object without modifying its children. Here's an example:
```javascript
const parentObj = {
name: 'John',
age: 30,
address: {
street: '123 Main St',
city: 'New York'
}
};
const updatedParentObj = Object.assign({}, parentObj, { age: 35 });
```
3. Use JSON.parse() and JSON.stringify(): If you have a deeply nested object and want to update the parent object only, you can use JSON.parse() and JSON.stringify() to achieve this. Here's how:
```javascript
const parentObj = {
name: 'John',
age: 30,
address: {
street: '123 Main St',
city: 'New York'
}
};
const updatedParentObj = JSON.parse(JSON.stringify(parentObj));
updatedParentObj.age = 35;
```
By using these techniques, you can easily update the parent object without affecting its children objects. This is useful when you want to maintain the structure of the object while making selective updates.
So there you have it! Now you know how to change only the parent object in JavaScript. I hope you found this helpful. Happy coding!
