Question

I am transmitting a function from an object to an array. However, when I attempt to calculate the sum of the array, the

Below is the provided code snippet:

var myObject = {
  x: 5,
  h: function(){
     varOne = 2*2;
     varTwo = 3*2;
     varThree = varOne*varTwo;
     },
  d: 4
};

var g = myObject.h();
var xyz = g;
var abc = 2;
var efg = 3;
var somearray = [xyz,abc,efg];
var z =  0;
for(i=0; i<somearray.length; i++){
    z += somearray[i];   
}

The output is NaN. What could be the reason behind this? If I modify it to: h: function(){return 2*2;}, then there are no issues. As a newcomer to JS, I've been researching online for answers without success. Would using parseInt or parseFloat help in this scenario and if so, which variable would require it? Appreciate your assistance.

Answer 1

Answer №1

The function h is not returning any value, resulting in undefined which when added produces NaN. Try the following code:

h: function(){
   var varOne = 2*2;
   var varTwo = 3*2;
   return  varOne*varTwo;
 },

It's advisable to use the var keyword for defining variables within a specific scope to avoid global pollution.

Because you are assigning numerical values to the variables, there is no need to parse them using parseInt.
