JavaScript sails: how to get a value outside of the function

I'm trying to get count value from a function and want to store in outside of the function.

var count;      
client.count({
                index: 'employee',
                type: 'details',
            }, function (err, response) {
                    if(err){console.log(err)}
                    count = response.count
                    console.log(count);
    });

console.log(count ); I want to use this count outside of the function. Is this possible to do?

Answer:1

Try writing your code this way:

client.count({
                index: 'employee',
                type: 'details',
            }, afterCount);
function afterCount(err, count){
    if (err) console.log(err);
    // do whatever you want with count
    // if there's too much logic, split it into functions and send count as a param to them
}
