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

Use parseInt() function javascript

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

Answer 2

Use parseInt() javascript function....

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

This looks the 'x' which you mention come dynamically has a string type. Just check the "typeof x".

Answer 3

Try with parseInt:

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

Answer 4

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];

JSFiddle demo.

Answer 5

Try this one:

var total = 0;
for (var i = 0; i < someArray.length; i++) {
    total += someArray[i] << 0;
}
