as well as this one also https://github.com/es-shims/es5-shim

And I am facing following issue IE browser : Undefined modelName for model

here is code for issue is coming up .

ModelStore.prototype = Object.create(Super.prototype); ModelStore.prototype.constructor = ModelStore;

ModelStore.prototype.set = function(model) { var existingAttrs, id, key, modelName, newAttrs;

id = model.get(model.idAttribute); modelName = this.modelUtils.modelName(model.constructor); if (modelName == null) { throw new Error('Undefined modelName for model'); }

the issue here is that when modelName is returned as an empty string, IE doesn't see it as a string, it is undefined. We monkey patched it so that f (modelName == null) { used a strict check, f (modelName === null) {

modelUtils.modelName is below.

ModelUtils.prototype.modelName = function(modelOrCollectionClass) {
  return this.underscorize(modelOrCollectionClass.id || modelOrCollectionClass.name);
};

But Function.prototype.name is unsupported by IE. (ES2015 standard), should be fixed.
