circle-to-polygon/input-validation/validateNumberOfEdges.js

Receives a Coordinate, a Radius and a Number of edges and aproximates a circle by creating a polygon that fills its area

exports.validateNumberOfEdges = function validateNumberOfEdges(numberOfEdges) {

    const ARGUMENT_TYPE = Array.isArray(numberOfEdges) ? "array" : typeof numberOfEdges;
    throw new Error(`ERROR! Number of edges has to be a number but was: ${ARGUMENT_TYPE}`);
  }

  if (numberOfEdges < 3) {
    throw new Error(`ERROR! Number of edges has to be at least 3 but was: ${numberOfEdges}`);
