Need clarification on Dust js array

Am new to dust template and to know the solution for this problem

I would like to iterate through this view context and get only the relative and friends arrays first item.

{
  Relative: "ravi",
  friends: [
    { name: "Moe", age: 37 },
    { name: "Larry", age: 39 },
    { name: "Curly", age: 35 }
  ]
}

You can accomplish using the @eq helper, available in the LinkedIn fork of Dust.

{Relative}{~n}
{#friends}
  {@eq key=0 value="{$idx}" type="number"}
    {name} {age}
  {/eq}
{/friends}

You still loop through the entire array, but only output name and age if the array index ($idx) is 0.
