Using a for loop when calling a method


Using a for loop when calling a method

To fix the issue you can do I'm using a for loop in a method to carry the result to the main function. I'm trying to use the for loop to get the month of a year and pass it on to the output from the main function. , You could make this cleaner by using switch
code :
 switch (month)
        {
            case 0: return "January";
            case 1: return "February";
            case 2: return "March";
            case 3: return "April";
            case 4: return "May";
            case 5: return "June";
            case 6: return "July";
            case 7: return "August";
            case 8: return "September";
            case 9: return "October";
            case 10: return "November";
            case 11: return "December";
            default: return "N/A";
        }

will be helpful for those in need At this point, speed isn't important (insert premature-optimization comment ;). What matters is how quickly you can understand what the code does, which is to call a method dicePool times.
The first method allocates an array of size dicePool and iterates through its values, which happens to run the loop body dicePool times (I'll pretend you meant int instead of Integer to avoid the unrelated autoboxing issue). This is potentially inefficient for the computer running the code, but more importantly it's inefficient for the human reading the code as it's conceptually distant from what you wanted to accomplish. Specifically, you force the reader to think about the new array you've just made, AND the value of the variable a, which will be 0 for every iteration of the loop, even though neither of those are related to your end goal.

I think the issue was by ths following , Here's the problem... , Upon closer inspection there are two things going wrong here.
code :
arrayoftotals.each do |convert_to_float|
end
arrayoftotals.each (&method (:convert_to_float)) 
def convert_to_float(currency)
  return currency.gsub(/regex/, "").to_f
end

def verify_amounts(total,subtotal,tax)
  arrayoftotals = [total,subtotal,tax]
  arrayoftotals.map! (&method (:convert_to_float)

  ftotal = arrayoftotals[0]
   raise "ftotal must be a Float" unless ftotal.kind_of? Float

end

this one helps. As functional programming language, XQuery's variables are immutable, think of them as constants that get hidden if redefined for the current scope.
Loops in XQuery are only used to work on all members of a sequence, not to repeatedly apply operations to a (repeatedly changed) value.

To fix this issue Use equals() method to compare strings. "==" checks only reference not the content of the string.
Is there some way to use .bind or .apply to give a called method the scope of the calling method or loop?

Does that help No. Scope in Javascript is lexical (based on the position of the code). You cannot change the scope of a function that is already declared.
You can however simply pass itemA to outerFunction as an argument when you call it. That is the usual and expected way to solve a problem like this.
