Javascript's equivalent of destruct in object model

Question

Since I\'ve dealt in the past with javascript\'s funky \"object model\", I assume there is no such thing as a destructor. My searches were mildly unsuccessful, so you guys a

Answer 1

In other languages the destructor is handy for implementing the memento pattern. That's actually what lead me to this topic. For example, in a click event it'd be nice to have a generic function that I can pass the event target to that disables the target and then re-enables it when it falls out of scope. Consider a submit button that does something like this:

function async saveMyStuff(e) {
    const sleeper = new nap(e)
    let data = await fetch(...)
    // a bunch more code.
}

class nap {
    constructor(e) {
      this.button = e.currentTarget
      this.button.disabled = true
    }
    destructor() { this.button.enabled = true }

}

This kind of construct would give me a oneliner that handles enabling/disabling all of my buttons when I'm talking to the backend or doing any other processing. I don't have to worry about cleaning up if I return somewhere in the middle or anything like that.
