calculate distance between two coordinates latitude longitude

Recently I used the formula for calculating the distance between two points on the earth's surface based on latitude and longitude, and then implemented it using JS. Based on the fact that the earth is a smooth sphere and not a real sphere, there are two ways to expand the sphere. If you are interested, you can use JavaScript to

I did not know this for a long time. I forgot it. I saw it in a book before. But what I found on the Internet was actually a spherical distance algorithm. Lat is the latitude, and lung is the longitudeA = Lat1-Lat2 is the difference between two points of latitude B = Lung1-Lung2 is the difference between two points of longit
