Update object key using destructuring


By : Sky Blue
Date : July 30 2020, 05:00 AM
like below fixes the issue Later property names will overwrite earlier property names. Just like a duplicate name below results in the last one being included in the object:
code :
console.log({
  name: 'foo',
  name: 'bar'
});
user1 = {...user, name}

Javascript: Reverse object destructuring / refactoring code to update object


By : Igor Sivak
Date : March 29 2020, 07:55 AM
like below fixes the issue If you want to assign the destructured value to a property, you do that by specifying the property on the right-hand side of a : in the destructuring.
For instance: The following assigns newObj.a and newObj.c to oldObj.a and oldObj.c:
code :
({a: oldObj.a, c: oldObj.c} = newObj);
//   ^^^^^^^^-----^^^^^^^^---- destinations for a and c
const oldObj = {a: "old a", b: "old b"};
const newObj = {a: "new a", c: "new c"};
({a: oldObj.a, c: oldObj.c} = newObj);
console.log(oldObj);
oldObj.a = newObj.a;
oldObj.c = newObj.c;

How to solve Error Use object destructuring prefer-destructuring - React

I wish this help you Your code can be improved to something like below. Please find relevant comments in the code below for your better understanding
code :
   handleCheckChildElement(event) {
           const { items } = this.state; //extract state values like this to a const variable 
           const newItems = items.map(item => { //do map on items because map returns a new array. It’s good practice to use .map than forEach in your case
                if(item.value === event.target.value) {
                         item.isChecked = event.target.checked;
                         return item; //return updated item object so that it will be pushed to the newItems array
                }
                return item; // return item because you need this item object as well
            });
           this.setState({ items: newItems}); //finally set newItems array into items
          }

Difference between object destructuring and and destructuring assignment?


By : R.Oliveira
Date : March 29 2020, 07:55 AM
help you fix your problem You need parentheses around the destructuring assignment do distinguish destructuring from a block statement where an assignment to it is not possible.
Assignment without declaration:
code :
let obj = { a: 1, b: 2 };
let a = 3, b = 4;

({ a, b } = obj);
console.log(a, b); // 1, 2
