Question

Name the property used in -15×30 is an integer​

Answer 1

Answer:

A property has a key (also known as “name” or “identifier”) before the colon ":" and a value to the right of it.

In the user object, there are two properties:

The first property has the name "name" and the value "John".

The second one has the name "age" and the value 30.

The resulting user object can be imagined as a cabinet with two signed files labeled “name” and “age”.

We can add, remove and read files from it any time.

Property values are accessible using the dot notation:

// get property values of the object:

alert( user.name ); // John

alert( user.age ); // 30

The value can be of any type. Let’s add a boolean one:

user.isAdmin = true;

To remove a property, we can use delete operator:

delete user.age;

We can also use multiword property names, but then they must be quoted:
