Step by Step solution about How to resolve the algorithm Currency step by step in the JavaScript programming language

This JavaScript code is used to calculate the total cost of hamburgers, shakes, and associated taxes for a given order.

Here's a detailed breakdown of the code:

1. Importing the 'money-math' library:

   const money = require('money-math')

   This line imports the 'money-math' library, which provides functions for performing monetary calculations.

2. Defining the initial values:

   • hamburgers: The number of hamburgers ordered (400,000,000,000,000)
   • hamburgerPrice: The price of each hamburger ($5.50)
   • shakes: The number of shakes ordered (2)
   • shakePrice: The price of each shake ($2.86)
   • tax: The tax rate (7.65%)

3. Calculating the total cost of hamburgers and shakes:

   • hamburgerTotal: The total cost of the hamburgers (calculated by multiplying hamburgers by hamburgerPrice)
   • shakeTotal: The total cost of the shakes (calculated by multiplying shakes by shakePrice)

4. Calculating the subtotal:

   • subTotal: The sum of hamburgerTotal and shakeTotal

5. Calculating the tax amount:

   • taxTotal: The amount of tax (calculated by applying the tax percentage to subTotal)

6. Calculating the total cost:

   • total: The sum of subTotal and taxTotal

7. Printing out the results: The code uses console.log statements to print out the following information:

   • Hamburger Total: The total cost of the hamburgers
   • Shake Total: The total cost of the shakes
   • Sub Total: The sum of the hamburger and shake totals
   • Tax: The amount of tax
   • Total: The final total cost of the order
