<pre><code>const prettify = (str) =&gt; {
  try {
    if (typeof str === 'string') {
      JSON.parse(str) // &lt;-- Invalid JSON passed. Code execution jumps to catch block (if any)
      return "prettified" // &lt;-- Does NOT get executed
    }
  } catch (e) {
    return "errored" // &lt;-- Is executed. However, finally overrides the return value.
  } finally {
    return str // &lt;-- Always executed. If it returns a value, it overrides any return value from try and catch block
  }
}

console.log(prettify('BFE.dev')) // 'BFE.dev' 
console.log(prettify('123')) // '123'
</code></pre>

finally block is always executed. It overrides the returns value of try and catch block.

What does the code snippet to the right output by console.log?…
