// type-1
var do_maths_add_two_number = function(val_one, val_two){ /*...*/ };
do_maths_add_two_number(10, 90); // Calling type-1

/// can be re-written as

// type-2
var do_maths = function(params){ /*...*/ };
do_maths({ mode : 'add', values[10,90]});  // Calling type-2
// OR
do_maths({"add" : [10,90]});  // Calling type-2

/// So longer name can be shorten still keeping its meaning and structure.
