Node.js async.times(To handle for loop in better way)


Example

To execute a function within a loop in node.js, it's fine to use a for loop for short loops. But the loop is long, using for loop will increase the time of processing which might cause the node process to hang. In such scenarios, you can use: asycn.times

function recursiveAction(n, callback)
{
    //do whatever want to do repeatedly
    callback(err, result);
}
async.times(5, function(n, next) {
    recursiveAction(n, function(err, result) {
        next(err, result);
    });
}, function(err, results) {
    // we should now have 5 result
});

This is called in parallel. When we want to call it one at a time, use: async.timesSeries
