a b and c are parameters ,here b and c are assigned default values in case user don't provide an argument for them but for the first input a we want a value from user so we aren't assigning ant default value to it , also if it was like a=4 passing 5 would override the previous value 4 and 5 would be the value for a

Please clarify your question what u asking about thia program output will be 50 . console.log(test(5) ) when here test function called so control will move to test function here b and c is also intilize so a will he automatically 5 after in return statement there is a+b+c means 5+3+42 total 50
