Inserting object literal into array

I don't understand why the splice method isn't working for me. I have an array that looks like: (it is actually bigger but I didn't want to clutter the page)

var navItems = [ {
                    "content": "Panels",
                    "icon": "panels"
                },
                {
                    "content": "Samples",
                    "icon": "sample"
                }];

I want to insert an item say in the middle:

var testNavItems = navItems.splice(1, 0, {
                    "content": "New Nav",
                    "icon": "New Nav"
                   });
console.log(testNavItems);

OR

var testNavItems = navItems.push({
                    "content": "New Nav",
                    "icon": "New Nav"
                   });
console.log(testNavItems);

I get an empty array. Is this possible in JS?

.push and .splice do not create a new array. They modify the original array.

Try 

console.log(navItems);
