**Formula:** `P = ∏ a`

where a_{i}_{i} are the terms to be multiplied.

The product notation (also known as the capital Pi notation) in mathematics is used to indicate the product of a sequence of terms. This is similar to how the summation notation (capital Sigma notation) is used for the sum.

In the JavaScript function provided, the '...args' parameter is used to take a variable number of arguments representing the terms in the product sequence, and the 'reduce' method is used to calculate the product of all the terms passed.

This function can be used to compute the product of a series of numbers in various mathematical and practical applications, like determining the total number of combinations, multiplying polynomials, and more. The result is given by multiplying all the numbers in the sequence together.
