using seamless-immutable in a jsbin about seamless-immutable

[rtfeldman]

Hm...seems to work fine in a Node REPL:

> var Immutable = require("seamless-immutable")
undefined
> var array = Immutable(["foo", "foo2", "bar", "bar2", "baz", "baz2"]);
undefined
> array
[ 'foo', 'foo2', 'bar', 'bar2', 'baz', 'baz2' ]

My first guess would be that Ember modifies Array.prototype in some way that is incompatible with seamless-immutable...do you know if that's something Ember does?

Yes, you are right, ember does modify the prototype. You can turn that off though.

Thanks

I've stopped ember extending the prototypes and I get a new error:

Uncaught ReferenceError: process is not defined

Which references this code:

    if (process.env.NODE_ENV === "development") {
      // Make all mutating methods throw exceptions.
      for (var index in bannedMethods) {
        banProperty(obj, bannedMethods[index]);
      }

Is this library node only?

Here is the updated jsbin

@dagda1 This is happening because you're importing the seamless-immutable source, not the compiled version (which has process stripped out). Try importing one of these instead:

seamless-immutable development mode (with freezing and helpful exception messages)
seamless-immutable production mode (minified, and runs faster, but doesn't freeze objects or offer helpful exception messages)

@dagda1 Did this fix the issue you were having?

[dagda1]

Sorry, yes, thanks
