Is is possible to autorun even when value doesn't change?

Question

For example

var x = observable({lastPressedKey:""});
autorun(() => console.log(x.lastPressedKey));
x.lastPressedKey = "spacebar"
x.lastPressedKey = "spacebar"
x.lastPressedKey = "spacebar"

I want that console.log prints "spacebar" three times. I can do something like this

x.lastPressedKey = ["space", Date.now()]
x.lastPressedKey = ["space", Date.now()]
x.lastPressedKey = ["space", Date.now()]

Is there a better way?

Answer 1

The whole point of an observable is to actually avoid what you are trying to achieve. However, you could change the lastPressedKey from a string to an object that includes the datetime, so it would trigger a rerender when the datetime changes even if the string stays the same.
