I have two variables that I would like to add in javascript but unfortunately I cannot find the syntax.

Example:
toto = '1';
tata = '2';
result = toto + tata;

return result;

Unfortunately the result obtained is 12 whereas I would like it to be 3.

Do you have an idea ?

Thanks in advance.

You placed the 1 and 2 between '' in the variables.

Then it's a sort of name instead of a number, and cant be calculated. It simply places the names after eachother. So you get 12. When you name them x and y you get xy

Without the '' it becomes a number

This should work:

 

var toto = 1;
var tata = 2;
var result = '';

result = toto+tata;

return result;

 

or:

 

var toto = 1;
var tata = 2;

return toto+tata
