 A step definition’s *expression* can either be a regular expression or a [cucumber expression](https://github.com/cucumber/cucumber-expressions#readme). The examples in this section use cucumber expressions. If you prefer to use regular expressions, each *capture group* from the match will be passed as arguments to the step definition’s function.

-Given(/I have {int} cukes in my belly/, (cukes: number) => {});
