var printNumTwo;
for (var i = 0; i < 3; i++) {
  if (i === 2) {
    printNumTwo = function() {
      return i;
    };
  }
}
console.log(printNumTwo());

This is the 3rd code snippet under " Compare Scopes of the var and let Keywords

I dont understand why printNumTwo has ‘()’ in console.log() in last statement.

2

printNumTwo is a function. The ()s call the function.

3

isnt it declared as var, and then assigned the value of function() ?

4

A function is stored in a variable just like any other type of JS object.
