How do I check an array for empty strings?

  You want to check the array for empty strings.
  I wrote it like this, but I feel that it can be more beautiful.
  How?
  

  json.reduce((result, current) => result || current[0]==="")

  arr.some (item = & gt; item === '')
  
  Or like this:
  
  arr.some (item = & gt;! item)
  
  In the second case, all `null`,` undefined` and everything that converts to `false` will also be found
