Inside a Function Call

  • Thomas Mailund


When you execute the body of a function, as you have seen, you do this in the evaluation environment. This evaluation environment is linked through its parent to the environment where the function was defined and has its arguments stored as promises that will be evaluated either in the environment where the function was defined (for default parameters) or in the environment where the function was called (for parameters provided to the function there). In the previous chapter, you saw how you could get hold of the formal parameters of a function, the body of the function, and the environment in which the function was defined. In this chapter, you will examine how you can access these, and more, from inside a function while the function is being evaluated.
