javascript - Inserting object literal into array -

I do not understand why the wedding method is not working for me I have an array that looks : (It really is big but I did not want to dislodge the page)

{{"content": "panel", "icon": "panel"}, { "Content": "samples", "icon": "sample"}];

I want to say one item in the middle:

  var testNavItems = navItems.splice (1, 0, {"content": "new neo "," Icon ":" new app "}); Console.log (testNavItems);   
 OR  
  var testNavItems = navItems.push ({"Content": "new av", "icon": "new app"}); Console.log (testNavItems);   
 I get an empty array, is it possible in JS?   
 
 
  .push  and  .splice  no new Do not array them, they modify the original array.  
 Try  
  console.log (navItems);
