State or Province?

Putting a state or province could be a smart thing to do....

Not fetching the correct cities

I live in BC Canada, my lat/long (49.119626, -122.691090) and the result I'm getting are cities from Winnipeg, 2.287km away from me. Something needs to be checked in your code.


   let listOfCities=[]
    const latitude = 49.119626;
    const longitude = -122.691090;
    listOfCities = nearestCities(latitude, longitude,[,5]);
