Sort of:

var key = "myKey"; myArray.push( { key : value} );

I know that you can:

 var key = "myKey"; var obj = {}; obj[key] = value; myArray.push(obj);

But it does not fit, since it is for me when I create the object I need to refer to the key.

    Ok, in ES6, you can:

     var key = "myKey"; myArray.push( { [key] : value} );
