JavaScript: Volume of a Sphere

JavaScript Math: Exercise-63 with Solution

Write a JavaScript program to calculate the volume of a Sphere.

From Wikipedia -
A sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.That given point is the centre of the sphere, and r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.

Sample Solution:

JavaScript Code:

// Define a function volume_Sphere that calculates the volume of a sphere given its radius.
const volume_Sphere = (radius) => {
  // Check if the radius is a number and positive.
  is_Number(radius, 'Radius');
  // Return the volume of the sphere.
  return (4 / 3 * Math.PI * radius ** 3);
}

// Define a function is_Number that checks if a given value is a number and positive.
const is_Number = (n, n_name = 'number') => {
  // If the given value is not a number, throw a TypeError.
  if (typeof n !== 'number') {
    throw new TypeError('The ' + n_name + ' is not Number type!');
  } 
  // If the given value is negative or not a finite number, throw an Error.
  else if (n < 0 || (!Number.isFinite(n))) {
    throw new Error('The ' + n_name + ' must be a positive values!');
  }
}

// Call the volume_Sphere function with valid and invalid arguments and output the results.
console.log(volume_Sphere(4.0));
console.log(volume_Sphere('4.0'));
console.log(volume_Sphere(-4.0));

Output:
