1799287 - Order of Function properties

Status: RESOLVED DUPLICATE of bug 1629803

(Core :: JavaScript Engine, defect)

Description

[f52985]

Steps to reproduce:

Execute the program below using jsshell

function f(){}
console.log(Object.getOwnPropertyNames(f));

Actual results:

"prototype,length,name"

is printed.

Expected results:

"length,name,prototype"

should be printed.

According to the ECMA-262 Specification, the algorithm DefinePropertyOrThrow is called with arguments "length", "name", and "prototype" in this order, so this order should be preserved when listing the properties with Object.getOwnPropertyNames.

Thanks for the report. If we fix this it would probably be part of bug 1629803.
