A call is the invocation of a function.
How many ‘calls’ can happen at once?
Only one call can happen at a time.
What does LIFO mean?
Last In, First Out. It means that the last function to get pushed into the call stack is the first to be popped out.
Draw an example of a call stack and the functions that would need to be invoked to generate that call stack.

What is a breakpoint?
A line in the code you specify which you want the interpreter to pause on before moving forward so you can review everything that has happened from the code up until that point.
What does the word ‘debugger’ do in your code?
