export a function for locations comparing

[chentsulin]

Does exists any functions can we compare equal between two locations?

Maybe should exist a function like this:

export function locationEquals(location1, location2) {
  if (location1 && location2 && location1.key && location2.key) {
    return location1.key === location2.key;
  }
  return false;
}

We already have a locationsAreEqual function, but that implementation is used specifically to determine whether or not the location has changed, which is slightly different. That function should probably be called locationHasChanged(prevLocation, nextLocation).

Is that what you need? What are you doing with it?

I need a function to compare between a location in redux store's state and a location in routing context, so that I can sync them by dispatch a action on location change or transitionTo new location on state change.

Just re-reading through your use case here.

When you get a new location in your redux dispatch, you can just call history.transitionTo(location) without worrying about whether or not the location is actually different. We already take care of that for you. So, let history worry about whether or not it actually needs to do something.
