How to change boolean value in localStorage?

Question

JavaScript

Hello. I have such a task. When I click on the button, I write to local.push {isOpen: true}
And when I click again, these records are simply duplicated, but how can I make only 1 record and manipulate it by changing it to true-false?

Answer 1

el.addEventListener('click', () => {
    const value  =  !localStorage.getItem('isOpen')
    localStorage.setItem('isOpen', value)
})

Answer 2

Hold
