Understanding the JS Call Stack

1. What is a ‘call’? - primarily used for calling functions - call stack is synchronous
2. How many ‘calls’ can happen at once? - functions are called one at a time from the top to the bottom
3. What does LIFO mean? - Last In, First Out
4. Draw an example of a call stack and the functions that would need to be invoked to generate that call stack.
5. What causes a Stack Overflow? - when a recursive function (a function which calls itself) doesn’t have an exit point

JS Error Messages

1. What is a ‘refrence error’? - a variable that is not yet declared
2. What is a ‘syntax error’? - code cannot be parsed because it was typed out wrong
3. What is a ‘range error’? - when an object with a length is given an invalid length
4. What is a ‘tyep error’? - This great pun is in fact not axample of a ‘type’ error but a syntax error! - type errors show up when the types of data being accessed are incompatible
5. What is a breakpoint? - an intentional stopping point in a program which helps assist in narrowing down the lo0cation of bugs/errors
6. What does the word ‘debugger’ do in your code? - it is a built-in breakpoint
