Compiling and deploying contracts
Ethereum provides the solc compiler, which provides a command-line interface to compile .sol files. Visit http://solidity.readthedocs.io/en/develop/installing-solidity.html#binary-packages to find instructions to install it and visit https://Solidity.readthedocs.io/en/develop/using-the-compiler.html to find instructions on how to use it. We won't be using the solc compiler directly; instead, we will be using solcjs and Solidity browser. Solcjs allows us to compile Solidity programmatically in Node.js, whereas browser Solidity is an IDE, which is suitable for small contracts.
For now, let's just compile the preceding contract using a browser Solidity provided by Ethereum. Learn more about it at https://Ethereum.github.io/browser-Solidity/ ...
