Some internal function conflict with user define function name "delete"

[emptizen]

When the function of x-data is named delete, Alpine will report the following error, for detailed stack trace please see here https://jsfiddle.net/ntve9org/2/. If I changed it to another name, everything was fine.
I don't know if there are any internal functions/properties that might conflict with user-defined function names,

"Alpine Expression Error: Unexpected token '}'

Please refer https://jsfiddle.net/ntve9org/2/ to see the full detail.

I am new to Javascript as a backend developer, surprised that delete is reserved word in Javascript! 😰

Yeah it's used for deleting a property off of an object. So that it won't be there at all.

It's the only way to mutate an object to remove a key.
