Remove a property from a JavaScript object

The delete operator is used to remove a property from a JavaScript object. It returns true if the property is removed successfully, otherwise false.

const fruits = {
    orange: '🍊',
    lemon: '🍋',
    kiwi: '🥝',
    mango: '🥭'
}

delete fruits.kiwi
// OR
delete fruits['kiwi']

console.log(fruits)
// { orange: '🍊', lemon: '🍋', mango: '🥭' }

The delete operator works with both dot notation (.) and square bracket ([]) notation.
