// declare an object using const

const myObject = {a: 1, b: 2, c: 3}

/*

add update an existing property

and add a new property to myObject

and no error will occur, because

we did not "reassign" new values

directly to the myObject variable using `=`

*/

myObject.c = 30

​

console.log(myObject) // { a: 1, b: 2, c: 30, d: 4}

/*

However, uncomment the line below and observe

the error when we attempt to "reassign" values

directly to myObject

*/

// myObject = {e: 5, g: 6} // an error will occur
