To run this recipe, we will need a script that accesses phantom.version. The script in this recipe is available in the downloadable code repository as recipe01.js under chapter02. If we run the provided example script, we must change to the root directory for the book's sample code.

Consider the following script:

console.log('PhantomJS');
console.log('  - major version: ' + phantom.version.major);
console.log('  - minor version: ' + phantom.version.minor);
console.log('  - patch version: ' + phantom.version.patch);
phantom.exit();

Given the preceding script, enter the following at the command line:

phantomjs chapter02/recipe01.js

Our output should look like the following:

PhantomJS
  - major version: 1
  - minor version: 9
  - patch version: 2
