How to loop through an array containing objects and access their properties

I want to cycle through the objects contained in an array and change the properties of each one. If I do this:

for (var j = 0; j < myArray.length; j++){



The console should bring up every object in the array, right? But in fact it only displays the first object. if I console log the array outside of the loop, all the objects appear so there's definitely more in there.

Anyway, here's the next problem. How do I access, for example Object1.x in the array, using the loop?

for (var j = 0; j < myArray.length; j++){



This returns "undefined." Again the console log outside the loop tells me that the objects all have values for "x". How do I access these properties in the loop?

I was recommended elsewhere to use separate arrays for each of the properties, but I want to make sure I've exhausted this avenue first.

Thank you!

Use forEach its a built in array function

yourArray.forEach( function (arrayItem)
    var x = arrayItem.prop1 + 2;
