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: “We have a host command and a ghost party. Writing this line of code could potentially take the host command from the ghost string.”

A block of code is set as follows:

Set JOURNEY="Attend Ghost"; yarn ch15
if (journey.includes(" host").toLowerCase()) {
// Host path being taken in error.
}

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

[0-0] ---> Clicking button[type="submit"] ...
[0-0] ---> button clicked.
[0-0] ---> pageSync() completed in 25 ms
[0-0] ---> Clicking button[type="bogus"] ...
[0-0] ---> button[type="submit"] was not clicked.
[0-0] Error: Can't call click on element with selector "button[type="bogus"]" because element wasn't found

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “In this example, the user does not attend the party and instead clicks the I’m scared button.”
