The class is now initialized with the prototype specified by extends and implementation specified by constructor.Private instance methods and accessors are saved to be installed on the instance directly later. Instance methods and accessors are installed on the prototype property of the current class, and static methods and accessors are installed on the class itself. Methods and accessors are installed in the order of declaration.None of the property values are evaluated yet. If the property key is computed, the computed expression is evaluated, with the this value set to the this value surrounding the class (not the class itself). The class elements' property keys are evaluated in the order of declaration.However, because the constructor definition is only a method definition, this step is not observable. The constructor method is extracted, substituted with a default implementation if constructor is not present.It must evaluate to a valid constructor function or null, or a TypeError is thrown. The extends clause, if present, is first evaluated.When a class declaration or class expression is evaluated, its various components are evaluated in the following order: Warning: unreachable code after return statement.Warning: -file- is being assigned a //# sourceMappingURL, but already has one.TypeError: X.prototype.y called on incompatible type.TypeError: setting getter-only property "x".TypeError: Reduce of empty array with no initial value.TypeError: property "x" is non-configurable and can't be deleted.TypeError: invalid assignment to const "x".TypeError: invalid 'instanceof' operand 'x'.TypeError: cannot use 'in' operator to search for 'x' in 'y'.TypeError: can't redefine non-configurable property "x". ![]() TypeError: can't delete non-configurable array element. ![]() TypeError: can't define property "x": "obj" is not extensible.TypeError: can't convert BigInt to number.TypeError: can't assign to property "x" on "y": not an object.TypeError: "x" is not a non-null object.Synta圎rror: Using to indicate sourceURL pragmas is deprecated.Synta圎rror: unterminated string literal.Synta圎rror: unparenthesized unary expression can't appear on the left-hand side of '**'.Synta圎rror: unlabeled break must be inside loop or switch.Synta圎rror: Unexpected '#' used outside of class body.Synta圎rror: test for equality (=) mistyped as assignment (=)?. ![]()
