title: StartsWith() in an array
body: <p>Basically I am using the values  'FLD_STR_101' to retrieve my file. I have different field starting with 'FLD_STR_' so I cannot base my if statement on this specific field. What I would like is to to do is map and retrieve the field with FLD_STR...something like this</p>
  <pre><code>values[startWith('FLD_STR_')]
  
  </code></pre>
  <p>so then I will be able to check if the field starts with FLD_STR_ and then I will be able to differentiate the field depending on the type of each field(file, text ...)</p>
  <p>Here is what I have as an example so you can understand. It seems that I cannot inject the startsWith() inside the array like this. Any clue on how to achieve this ?</p>
  <pre><code>    const test =Object.entries(values['FLD_STR_101']).map((entry, key) =&gt;( {
              test: entry[0],
              test2:key
      }))
  
  </code></pre>
