Terminal state in ES6 destruction object

Question

Terminal state in ES6 destruction object

I wrote a stateless function, in this function I am using a Destructuring object declaration, but one of my variables has a condition. I wrote this with a triple condition. but I cannot declare it in the Destructuring assignment structure.

This is my declaration:

    const pageNo = props.filters.pageno
                     ? props.filters.pageno -1
                     : 0;

    const {
        data: {
            result: {
                total : total
            } = {}
        },
        tags: {
            result: {
                categoryFilter: {
                    Title : title
                } = {}
            } = {}
        }
    } = props;

        result: {
            total : total = 0
        } = {}
    }={},
    filters: {
         pageno: TempPageNo = 0
    }={},
    tags: {
        result: {
            categoryFilter: {
                Title : title = "something"
            } = {}
        } = {}
    }={}
} = props;

const pageno = TempPageNo ? TempPageNo - 1 : TempPageNo

You cannot directly. You can do:

const {filters: {pageno}} = props;
const realPageno = pageno ? pageno - 1 : 0;
