The Formula control allows you to define the calculation logic used by the Project Value Calculator. You can create complex formulas using conditional statements and variables. For example:

• Basic Calculation:

  • Formula: pages * 1000

  • Explanation: This formula multiplies the number of pages (input field named pages) by 1000. If you enter 5 in the pages field, the calculated value will be 5000.

• Conditional Calculation:

  • Formula: if (complexity === 'Easy') { pages * 500 } else { pages * 1000 }

  • Explanation: This formula checks the value of the complexity field. If the complexity is 'Easy,' it multiplies the number of pages by 500; otherwise, it multiplies them by 1000. For example, if you select 'Easy' and enter 4 pages, the value will be 2000.

• Nested Conditions:

  • Formula: if (type === 'Web') { if (complexity === 'Easy') { pages * 1000 } else { pages * 2000 } } else if (type === 'Mobile') { if (complexity === 'Easy') { pages * 100 } else { pages * 200 } } else { 0 }

  • Explanation: This more complex formula first checks the type of project (Web or Mobile). If it's a web project, it further checks the complexity and calculates the value accordingly. For instance, a 'Web' project with 'Easy' complexity and 3 pages would yield a value of 3000.
