If value matches another value in array display items JavaScript

I have a list of objects, in each object I have a date and time.

onClick of a td element (its a calendar) I check the time on the calendar, then check if it matches any times in my list of objects.

onSelect: function(date) {
    for (var i = 0; i < dateArray.length; i++) {
        for (var prop in dateArray) {
            if (date === dateArray[prop].date) {
                console.log(dateArray[prop].time);
            }
        }
    }
}

So I loop through my array, which is an array of objects. To be able to get anything out I need to do a for in loop, and in there I do a condional statement to say if the dates match. The console.log out the corect time.

However, the time gets console logged out 10 times since it's in a loop. But the only way I could get inside my object array was to loop through them.

How should I actually be doing this.

EDIT

dateArray structure: list of objects like [ object, object, object, object ] and once I loop through them, within each object it looks like :

Object {title: "The Title", date: "01/01/2017", time: "07:30pm", available: true,}

I think you are simply looping twice.

Given it is an array, you should loop it using for, like this

onSelect: function(date) {
    for (var i = 0; i < dateArray.length; i++) {
        if (date === dateArray[i].date) {
            console.log(dateArray[i].time);
        }
    }
}
