Parameters in Bosque are not a big surprise for any programmer who has used some of the popular programming languages. The majority (or even all) of the examples in the chapter will look very familiar if you have used languages such as JavaScript, TypeScript, or even Java and others. This is why we will go through this topic pretty quickly.
