How do I use jq to convert number to string? : <p>Given the following jq command and Json:</p>

<pre><code>jq '.[]|[.string,.number]|join(": ")' &lt;&lt;&lt; '
[
  {
    "number": 3,
    "string": "threee"
  },
  {
    "number": 7,
    "string": "seven"
  }
]
'
</code></pre>

<p>I'm trying to format the output as:</p>

<pre><code>three: 3
seven: 7
</code></pre>

<p>Unfortunately, my attempt is resulting in the following error:</p>

<blockquote>
  <p>jq: error: string and number cannot be added</p>
</blockquote>

<p>How do I convert the number to string so both can be joined?</p>
