I am loving using lambda functions in AWS. It ideally reduced my time in maintaining the servers anymore. My question is when using lambda there is context object and the callback function to terminate the function. Is there any use case of using callback over context.

Could anyone tell me the behavior of context.succeed() to callback(error,message)

var startedAt = new Date();



var interval = setInterval(function () {

    console.log(startedAt, new Date());

}, 1000);



exports.handler = function (event, context, callback) {

    setTimeout(function () {

        console.log('returning');

        // v1:

        return callback(null);

        // v2:

        // return context.succeed();

    }, 5000);

};
