Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

web3.eth.getAccounts(callback(error, result){ ... })

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

web3.eth.getAccounts()
  .then(function (accounts) {
    console.log(JSON.stringify(accounts, null, 2));
  })
  .catch(function (error) {
    console.error(error);
  });

Any command-line input or output is written as follows:

make geth
