How to filter an array which is inside an object which has other details as well-CodePudding

I have an object

const object = {
 name:'XYZ',
 Others: 'XYZ',
 numbers:[2,3,4,5,6,5]
}

I want to filter numbers array which is inside the object and return the object with filtered array like this in which array has numbers 5 only.

{
 name:'XYZ',
 Others: 'XYZ',
 numbers:[5,5]
}

If I use filter in JavaScript like this

object.numbers.filter()

It returns only numbers array not complete object with other details like name. What is the best way to implement it?

CodePudding user response：

Just assign object.numbers with filter return like:

const object = {
 name:'XYZ',
 Others: 'XYZ',
 numbers:[2,3,4,5,6,5]
};
object.numbers = object.numbers.filter(el => el === 5);
console.log(object);

CodePudding user response：

to make it work with this.setState you have to create a new Object:

let object = {
 name:'XYZ',
 Others: 'XYZ',
 numbers:[2,3,4,5,6,5]
}

let updatedObject = {...object,numbers:object.numbers.filter(e => e === 5)}
console.log(updatedObject)
// this.setState(updateObject)
