I have property yaCounter27352058 in window object.
I can easily get it using bracket notation
window["yaCounter27352058"]
The problem is that I don't know object id, so in general I want to get all objects like this
window["yaCounter*"]

You can query based of Object.keys:
var values = Object.keys(window).filter(function(el) {
return /^yaCounter.*?/i.test(el);
});
Then you can iterate:
values.forEach(function(key) {
console.log(key, window[key]);
});

Well, in fact you can't. But you can do something else.
You can try to list all your properties with
var properties = Object.keys(window).
Then with a regexp you will select your properties starting with yaCounter :
var reg = new RegExp("^yaCounter.*");
var goodProp = [];
properties.forEach(function(prop) {
if (reg.exec(prop) != null)
goodProp.push(prop);
}
And them use these with :
goodProp.forEach(function(val) {
window[val];
}));

exec only takes a string, so this would only match if the yaCounter variable was the first property on window which it's unlikely to be...

Yes you are right, exec should be called for each item of the properties array.
