I just wanted to eat some pasta.

Question

So I am the average Italian, and during Sundays all my family gathers to eat some pasta together.
I thought to make a code to calculate how many people are eating and how much pasta to cook could have been a good and simple idea.
And oh mamma mia if I wasn't mistaken.

In the code, I put in <input type ="number"> a value referring on how many grams of pasta a certain person is eating (default 80). When the checkbox is checked, I expected the number to be added to a variable later used to calculate the total grams. Instead it just adds "80" to the variable like it was a string.

- The issue is before the comment with many "!!!!!"
- You can ignore the second checkbox and form
- No we aren't 2 in the family

Thanks, this has been driving me insane for 3 hours.

Answer 1

And that's bcz 'value' will always return a string and not a number.
Just a little correction at line 30, you need to convert the 'value' to Number.

grams += Number(numAdd);

Answer 2

Matteo Consolaro to be rigjt it is class so you create new object of class Number, which is simply number
