how to queue functions using an array when functions are called

Question

I am coding in JavaScript and was wondering how I would go about queueing functions in an array when called until a execute function is called causing the rest of them to be calculated.

the code that I have for something like this and was just wondering if it would work.

addNegationTask(x)
{
   this.value = this.value * -1
   // this adds the equation to the array
   this.tasks.push(x => value * -1)
   return this.value;
}

I have other functions that follow a simular route, any answers on the matter would be greatly apriciacted.

I'm not sure its something that is being asked for on the brief that I have been given for this task. — modzking4, Jan 05 '19 at 15:06
What's the purpose of the `x` argument to `addNegationTask`? You never use it. — Barmar, Jan 05 '19 at 15:31

You need to put the assignment in the callback function.

addNegationTask()
{
   // this adds the equation to the array
   this.tasks.push(() => this.value *= -1)
}

I've removed the x argument, since it's not used for anything.
