| 27. Let staticFields be a new empty List. |
| 28. For each ClassElement e in order from elements, |

| ... |
| b. Else, |
| i. Let field be the result of performing PropertyDefinitionEvaluation for m ClassElementEvaluation for e with arguments F and false. |
| c. If field is an abrupt completion, then |
| ... |
| d. If field is not empty, |
| i. If IsStatic of e is false, append field to instanceFields. |
| ii. Otherwise, append field to staticFields. |

| 34. For each item fieldRecord in order from staticFields, |
| a. Perform ? DefineField(F, field). |
| ... |
| |
| DefineField(receiver, fieldRecord) |
| 1. Assert: Type(receiver) is Object. |
| 2. Assert: fieldRecord is a Record as created by ClassFieldDefinitionEvaluation. |
| 3. Let name be fieldRecord.[[Name]]. |
| 4. Let initializer be fieldRecord.[[Initializer]]. |
| 5. If initializer is not empty, then |
| a. Let initValue be ? Call(initializer, receiver). |
| 6. Else, let initValue be undefined. |
| 7. If fieldRecord.[[IsAnonymousFunctionDefinition]] is true, then |
| a. Let hasNameProperty be ? HasOwnProperty(initValue, "name"). |
| b. If hasNameProperty is false, perform SetFunctionName(initValue, fieldName). |
| 8. If fieldName is a Private Name, |
| a. Perform ? PrivateFieldAdd(fieldName, receiver, initValue). |
| 9. Else, |
| a. Assert: IsPropertyKey(fieldName) is true. |
| b. Perform ? CreateDataPropertyOrThrow(receiver, fieldName, initValue). |
