TypeError when using rest operator in function parameter destructuring

[reygreen1]

I encountered an error when using the rest operator when destructuring a function parameter.

My test source code like this:

var a = {name:'hi', age:11};
function foo(e={...a}){}

The error info like this:

TypeError: Cannot read property 'type' of undefined

I have tried the method in #11 , but it does not work. So any help?

Dependencies versions:

typhonjs-escomplex@0.1.0

I'll try and get a look at upgrading the underlying parser and fundamental AST processing soon which means likely January. From the stack trace it doesn't seem to be a code parser issue, but how the generated AST is handled. Alas when I made that last patch update in Dec '18 / Jan '19 I likely didn't include all the thorough use cases at the time in the tests.

I'm working on some new build tooling right now for Node modules that I need to complete first as I'll use this in the upgrade process to other TyphonJS modules. This issue should go away once I rebuild and upgrade the underlying Babel parser for escomplex and handle the AST processing of any of the newer language features.

I suppose the good news is that I'm back coding and certainly realize that some updates need to occur to escomplex and I appreciate you submitting this issue to light a bit of a fire behind getting these fundamental updates done. :D
