Conventions used

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

Code in text: 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: "Go to localhost:5000 in your browser to display home.html."

A block of code is set as follows:

for(var i = 0; i < relationship_list.length; i++) {
            var opt = relationship_list[i];
            select_relationship.innerHTML += "<option value=\"" + opt + "\">" + opt + "</option>";

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

cp -r deploy_image deploy_image_test

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select the Choose Files button to bring up the file selection dialog."
