can anyone give me an example in which we are creating a particular function, which is also having a callback function ?
function login(username, password, funct
bad question but w/e
you have mixed up invoking and defining an asynchronous function:
// define async function:
function login(username, password, callback){
console.log('I will be logged second');
// Another async call nested inside. A common pattern:
setTimeout(function(){
console.log('I will be logged third');
callback(null, {});
}, 1000);
};
// invoke async function:
console.log('I will be logged first');
login(username, password, function(err,result){
console.log('I will be logged fourth');
console.log('The user is', result)
});
