Nan Replacement In Node.js With An Integer

I am using following code to update database in node.js var mBooking = rows[0]; var distance = mBooking.distanceTravelled; var lastLng = mBooking.lastLng; var lastLat = mBooking.la

Solution 1:

Use isNaN().

if (isNaN(distance))
    distance = 0;

You can also condense this to one line with an inline-if:

distance = (isNaN(distance) ? 0 : distance);
