The JavaScript engine that evaluates server-side scripts supports the ECMAScript 2021 (ES12) standard.

No plugins or properties are required to install the new JavaScript engine.

The benefits of the new engine are:
  • Modern library code and scripting features, such as optional chaining, destructuring, const and let declarations, and arrow functions
  • Follows standard ECMAScript 2021 behavior

What to know

The JavaScript engine provides an improved environment for developing scripts.
  • Beginning with the Tokyo release, new and existing scoped applications can run in ECMAScript 2021 (ES12) mode.
  • Compatibility mode supports the legacy modifications to the legacy JavaScript engine.
