+ * @description Calculates the square root of a non-negative number
+ *   using the Babylonian (Newton's) method without using Math.sqrt().
+ * @param {number} n - A non-negative number
+ * @param {number} precision - Decimal places of precision (default: 10)
+ * @returns {number} - The square root of n
+ * @see https://en.wikipedia.org/wiki/Methods_of_computing_square_roots
+ * @example squareRoot(4) => 2
+ * @example squareRoot(9) => 3
+ * @example squareRoot(2) => 1.4142135624
