When to use .toJS() with Immutable.js and Flux?

Question

I\'m trying to use ImmutableJS with my React / Flux application.

My stores are Immutable.Map objects.

I\'m wondering at which point should I use

Answer 1

Good point raised by @Hummlas.

I personnally use it in my React components, when I iterate over a collections to render an array of sub components:

this.props.myImmutableCollection.map(function(item, index) {
    React.DOM.div null, item.get('title');
}).toJS();

If you don't use .toJS(), React won't recognize the mapped elements as an array of components.
