Um exemplo de projeto node com operações matemáticas

var call_counter = require('./contadorDeChamadas')

function add(x, y){    
    call_counter();    
    return x + y; 
} 

function subtract(x, y){    
    call_counter();    
    return x - y; 
}

// This module exports two functions, so an object is created to provide access to these functions. In this case, 
// the addition method references the add function, whereas the subtraction method references the subtract function. It’s more
// typical for the method name to be the same as the function name, but this example demonstrates that they can be different. 
module.exports = {    
    addition: add,    
    subtraction: subtract 
}
