how to find the radius of a loacation in node js

Finding the Radius of a Location in Node.js

To find the radius of a location in Node.js, you can use the Haversine formula, which calculates the distance between two points on a sphere given their latitude and longitude coordinates. Here are the steps to find the radius of a location in Node.js:

  1. Install the haversine-distance package by running the following command in your Node.js project directory: npm install haversine-distance

  2. Import the haversineDistance function from the haversine-distance package in your Node.js script: javascript const { haversineDistance } = require('haversine-distance');

  3. Define the coordinates of the two points: the center point and the location you want to find the radius for. For example: javascript const center = { latitude: 37.7749, longitude: -122.4194 }; const location = { latitude: 37.7749, longitude: -122.4194 };

  4. Use the haversineDistance function to calculate the distance between the two points: javascript const distance = haversineDistance(center, location);

  5. The distance variable will contain the radius of the location in kilometers.

Here's the complete code example:

const { haversineDistance } = require('haversine-distance');

const center = { latitude: 37.7749, longitude: -122.4194 };
const location = { latitude: 37.7749, longitude: -122.4194 };

const distance = haversineDistance(center, location);
console.log(distance);

Please note that you need to replace the latitude and longitude values in the center and location objects with the actual coordinates of the points you want to calculate the radius for.
