Class 10 Summary :
JavaScript Call Stack :
-
Call Stack : it is synchronous, excutes the function one at the time used for calling the function.
-
when calles function the interpreter add this function in call stack, when another function called by this function also added into call stack and excute when the calls reached. When the function finished the interpreter take it out call stack .
-
LIFO : (last in, first out) used to manage function calling. The last function enter call stack, it will be the first to be out.
-
Example of call stack :
- Stack overflow : caused when there is a function calls itself .
