call by value = only the value of the variable is given as a parameter. When you change the value in the function, nothing happens to the variable in the structure that calls our function.

All primitive data types are passed by value.(eg string, boolean, date, datetime, decimal etc)

 

call by reference = the reference to the variable is given as a parameter. This is the normal case. Anything the function changes with it, goes right back to the variable in the structure that calls our function.

Non primitive data types are passed by refernce(eg list, set, map)
