The document discusses JavaScript functions including function prototypes, lambda properties, and callback functions. Function prototypes define the name and arguments of a function. Lambda properties allow functions to be treated like variables by assigning them to a variable. Callback functions are functions passed into other functions to be executed later, like assigning a function to the window.onload event to run code when the page loads.

- 4. Lambda Property var func_ptr = function( arg0, arg1, …) { Similar to function ptr in C //function body return ret_val; } var ptr = func_ptr ; Treat function as variable!
- 5. Callback Function var call_back = function welcome() { alert(“welcome here"); } window.onload=call_back; No parentheses
