javascript - foor loop doesn't work correctly -

this lift programm:

var person = {    name: "roman",    position: 7,    goal: 9  };    var lift = {    getposition: function() {      var x = math.floor((math.random() * 10) + 1);      return x;    }()  };    console.log("ok " + person.name + "! @ " + person.position + " floor");  console.log("lift @ " + lift.getposition + " floor");    if (lift.getposition > person.position) {    (i = lift.getposition; >= person.position; i--) {      console.log(i);    }  } else if (lift.getposition < person.position) {    (i = lift.getposition; <= person.position; i++) {      console.log(i);    }  }  console.log("please enter inside!");

for loop raising lift doesn't work. lift falling not raising. what's wrong?

you've capitalized position in second loop.

should

for (i = lift.getposition; <= person.position; i++) { 

(with lowercase p in person.position)

since there no position property in lift object, loop condition asking if i <= undefined. evaluate false , therefore loop never iterates.
