Cocoscreator 2x IE Polyfill problem

Cocoscreator 2x IE Polyfill problem

Are you not officially supporting cos 2x IE?
getOwnPropertySymbols() is known as a function not supported by IE.
The engine polyfill course ‘object.js’ use the function above.

you can include babel package, i’ve asked this before here: Recommended Way To Include Babel Polyfill?

but i would be interested in an official solution as well :slight_smile:

babel/polyfill is not a workaround. There are no sub-compatible functions.

Look at the object.js engine code.
If Object.getOwnPropertyDescriptors() is not supported, the function is supposed to be overridden.
Problem writing Object.getOwnPropertySymbols() within function implementation.

For your information
Object.getOwnPropertyDescriptors() Supported on es2017 and IE Unsupported
Object.getOwnPropertySymbols() IE Unsupported
