What are the functional differences between Fabric Javascript SDK and Hyperledger Composer?

Question

除了Composer使原型业务网络的部署和测试变得更容易的事实以及我们不必知道golang来开发链码这一事实之外，这些接口提供的功能上的差异是什么，这可能导致人们选择其中一种另一个？

Hyperledger Composer is both an application development framework and set of powerful tools which simplifies and expedites the creation of blockchain applications and smart contracts that are ultimately executed on the Hyperledger Fabric blockchain. Composer has its own runtime, that is generic chaincode and hosts and interprets the business network deployed - so your smart contract need only use Javascript, not chaincode in Go a (which is Fabric's domain) s you mentioned. It also has a modeling facility to create your business network model and to define such controls as Access Control lists and queries to be executed.
