How do we add/remove properties to objects dynamically in JS?

JavaScript - Interview Questions

We can add a property to an object by using :

object.property_name =value

To delete a property, we can use :

object.property_name

Example :

   let user = new Object();

    // adding a property

    user.name=’ftl’;

    user.age  =22;

    console.log(user);

    delete user.age;
