Unlocking the Power of Variables: How to Calculate Discounts in JavaScript

An example with variables can be useful in real projects when you need to perform calculations based on data that can change. Imagine you are working on a discount system for an online store.

Example task: calculating the price of a product with a discount.

Here, const is used for the fixed product price, while let is used for the discount, which can change depending on promotions or conditions. This is a basic example that shows how working with variables allows for dynamically recalculating final values based on changing data.
