Summing array on Javascript

Question

Hi I am trying to sum an array on Javascript with the following codes.

var data[]: 
var total=0;
data.push[x]; // x is numbers which are produced dynamically. 
f         


        

Answer 1

Simply whip a unary + before data[i] to convert the string values to numeric values:

total = total + (+data[i]);

Even better, use += instead of total=total+...:

total += +data[i];
