If you look at the source code of a typical application, you will likely find business logic tangled with database calls, HTTP requests firing off in the middle of validation rules, and try/catch blocks sprinkled here and there. The biggest casualty of this coupling is testability…

In a typical imperative application, business logic and side effects are inextricably linked. For example, when you write await db.checkInventory(…), the runtime immediately reaches out to the database. Our Effect System works differently. Instead of performing the action, our functions return a description of the action. When our code needs to check inventory, it doesn’t call the database; it returns a plain object instead, which will be executed later by an interpreter.
