Bug ID: 247428
Summary: Reassigning to class name during static field
initialization
Product: WebKit
Version: WebKit Local Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: p51lee at kaist.ac.kr
// input.js
class x { static #y = { x = 0 } = 0 ; }
__________________________________________
Hello,
Executing the input.js using JSC throws ReferenceError.
However, it is expected to throw TypeError.
Running the input.js with JSC results in:
---
$ jsc input.js
Exception: ReferenceError: Cannot access uninitialized variable.
global code at input.js:1:1
---
while other engines behave like:
---
# V8
$ node input.js
input.js:1: TypeError: Assignment to constant variable.
class x { static #y = { x = 0 } = 0 ; }
^
TypeError: Assignment to constant variable.
at <static_initializer> (input.js:1:25)
at input.js:1:1
# GraalJS
$ js input.js
TypeError: Assignment to constant "x"
at <js> :initializer(input.js:1:24)
at <js> :program(input.js:1:0-38)

WebKit version: 615.1.10
