using variable const in an Object Literal.

In early courses, i thought i learned that using const variable, you couldn't change the value of that variable. and that i you want to change a value inside a variable its better to use let (or var)

but this code does run, how does it relate to that explanation about choosing the type of variable?

const person = { name: 'Edward', };

person.name= rachel; person.city = 'New York';

let message = hi my name is ${person.name}. I live in ${person.city};

document.write(message);

love to hear for you ! gr. Max

Since it was declared const, you cannot reassign "person". It will always refer to that object.

However, you can still add, remove, or alter the properties of the object. The properties are not constants.
