const obj1 = obj2;
obj1 is now a reference for obj2, it just pointing to obj2. So, modifying obj2 will also modify obj1
If you want to be able to modify obj1 freely, a simple solution is by destructuring:
const obj1 = {...obj2};
-
const obj3 = {a: 2, b: 3, c: 4}, and you want to exclude or delete the 'b' attribute? :
delete obj3['b'];
- Destructing with an alias!
const obj4 = {name: "Idris"};
if we want to set the name attribute to a new variable called username, we can do it like this:
const {name: username} = obj4;
console.log(username); // Idris
