Concurrency

Helper functions for dealing with concurrent requests.

axios.all(iterable)

axios.spread(callback) 

Use new ES6 feature: [...new Set( [1, 1, 2] )];

function uniqueArray0(array) {

  var result = Array.from(new Set(array));

  return result    

}

Use filter + indexOf

function uniqueArray3(a) {

  function onlyUnique(value, index, self) { 

      return self.indexOf(value) === index;

  }

  // usage

  var unique = a.filter( onlyUnique ); // returns ['a', 1, 2, '1']

  return unique;

}

// CHECK REQ VALIDITY

        if(!req.body["password"] || !req.body["name"]){

            result["success"] = 0;

            result["error"] = "invalid request";

            res.json(result);

            return;

        } 

app.get('/users/:id', (req, res) => {

  const id = parseInt(req.params.id, 10);

  if (!id) {

    return res.status(400).json({error: 'Incorrect id'});

  }

}); 

var w = $(window);

var row = $('#tableid').find('tr').eq( line );

if (row.length){

    w.scrollTop( row.offset().top - (w.height()/2) );

}
