What is JS: Business Rules?

JavaScript Business Rules (though not a formally defined technology or term in the same way as a specific library or framework) refers to the use of JavaScript to implement and manage business rules within applications. Business rules are statements that define or constrain some aspect of the business. They guide behavior, make decisions, and control processes. In JavaScript, this typically involves creating modular code that encodes these rules, often using conditional statements, functions, and data structures to represent and evaluate the rules based on input data. This allows for dynamic and configurable application logic without requiring code changes for every rule modification. Common uses include validating data, determining eligibility, calculating prices, and routing workflows. Implementation can vary widely, from simple if/else structures to complex rule engines built with JavaScript.
