es5-compliance

ServiceNow server-side scripts throw syntax errors when using ES6+ features because the Rhino engine requires ES5 compliance, meaning modern syntax like const, let, arrow functions, and template literals must be converted to their ES5 equivalents.

To convert modern JavaScript to ES5 for ServiceNow, use a compliance tool to automatically identify ES6+ syntax and replace const, let, arrow functions, and template literals with their ES5 alternatives, ensuring Rhino engine compatibility.

ServiceNow does not support ES6 JavaScript in server-side scripts because the platform uses the Mozilla Rhino engine, which strictly requires ES5 compliance to prevent deployment failures and runtime exceptions.

ES6+ JavaScript syntax causes runtime exceptions in ServiceNow, specifically const declarations, let declarations, arrow functions, and template literals, which must be converted to ES5 syntax to ensure compatibility with the Rhino engine.

You need ES5 compliance for ServiceNow Business Rules whenever writing new server-side scripts, as using modern ES6+ syntax without converting to ES5 alternatives will trigger SyntaxError exceptions and prevent successful deployment.

You cannot use arrow functions in ServiceNow Script Includes because the Rhino engine requires ES5 compliance, meaning arrow functions must be converted to traditional function expressions to avoid syntax errors.
