The formula editor is where you construct business logic for your application in Nordcraft. It provides a powerful yet accessible way to transform data, perform calculations and implement conditional logic throughout your application.

Formulas in Nordcraft are expressions that:

• Perform logical operations and data transformations
• Execute mathematical calculations
• Filter, search, and manipulate data
• Return consistent results for the same inputs

Formulas are pure functions, which means they:

• Have no side effects (don't modify external state)
• Always return the same output given the same input(s)
• Can be composed together to build more complex logic

The formula editor appears when editing formulas and wherever you see an fx button in the Nordcraft interface:

• In the attributes panel when binding values
• In the Show and Repeat sections
• In the style variables panel
• In the data panel when defining formulas
• ...

In the formula editor, you can:

• Reference variables, attributes, and other data
• Use built-in functions and operators
• Compose complex logic from simpler operations
• See live preview results as you type

For complex formulas, Nordcraft provides a full-screen view of the formula editor. It offers a larger canvas, better visibility of logic and easier navigation for formulas with many operations. To expand, click the icon button in the top-right corner.

Built on the modern web platform, Nordcraft offers many built-in formulas that closely align with similarly named JavaScript functions. Familiarity with these JavaScript concepts can help you create more effective formulas:

• Array methods (map, filter, reduce, etc.)
• Object methods (keys, values, entries, etc.)
