the console print "try again" although every thing is correct. what should i do? btw my code is same as yours

any one has the answer? it doesn't make any sense!

var bestApp = 'studytonight';
let _code = 'I love coding';
let num = 007;
let $123 = 100;

console.log(bestApp);
console.log(_code);
console.log(num);
console.log($123)

that's what the answer suppose to be, but it keeps printing an error notificatio :"(
i'd be relieved if anyone help me to put an end for this
