Truffle is a very popular development framework for Ethereum. It provides built-in smart contract compilation, a scriptable deployment framework, and a rich, automated contract testing platform. Truffle also provides an interactive console with the Ethereum network for direct contract communication. Truffle is completely based on JavaScript and is very modular. This allows you to use Truffle as a development platform or integrate it into your toolset to take advantage of its features.
Truffle is suited for anyone who wants a framework for Ethereum development so they can better organize their DApp and not have to worry about manually setting up a test environment.
