How to access array/object inside function in javascript ?

Question

Hello I have array outside function like below :

var daily = [];
daily["data"]=[];
daily["data"].push('hello');

function demo()
{
console.log(daily); // not working here
}

How to declare this object as global in Javascript ?

Answer 1

It could be because your function is being hoisted. Try this instead for your function.

var demo = function(){
  console.log(daily);
}

You might also considering just passing that daily variable into your function like so,

var demo = function(d){
  console.log(d);
}

then when you want to call it.

demo(daily);
