ES6 export default AssignmentExpression

Question

export default var foo = {...}

It's AssignmentExpression and valid es6 syntax? JSHint says it Expected an identifier and instead saw 'var'.

On last spec I not found any relation with VariableStatement and AssignmentExpression.

Are you sure you want var in there? It seems like you should just have export default foo or export var foo. I can't find any examples where they use export default var ... — Ian
The modules spec recently underwent big changes. I'd avoid ES6 modules in favor of something like requirejs if I were you.(at least for now) — Benjamin Gruenbaum

var foo = {...}

is not an AssignmentExpression. AssignmentExpression is almost the top level non-terminal symbol that represents all expression, i.e. basically every expression is an AssignmentExpression.

var only appears in a variable declaration or a for loop, so drop the var.
