filtering an array of objects using an array without nested loops js

I have been trying to figure out the cleanest way to filter an array of objects without using nested loops. I found this post using .filter function about filtering an array using another array but I failed on figuring out how to actually access the right key within the object in array of objects using the same pattern Given the next following array of objects:

[ { technology: 'CHARACTER', score: -1 },
{ technology: 'PRESSURE_RELIEF', score: 2 },
{ technology: 'SUPPORT', score: 3 },
{ technology: 'MOTION_ISOLATION', score: 2 },
{ technology: 'TEMPERATURE_MANAGEMENT', score: -1 },
{ technology: 'COMFORT', score: 2 } ]

I want to use the following array to filter the ones I don't need:

[CHARACTER, MOTION_ISOLATION, TEMPERATURE_MANAGEMENT]

Is it even possible to access it without using a nested loop? I'm also open to suggestions if not possible.

You can use .filter with .indexOf like so 

var condition = ['CHARACTER', 'MOTION_ISOLATION', 'TEMPERATURE_MANAGEMENT'];

var data = [ 
  { technology: 'CHARACTER', score: -1 },
  { technology: 'PRESSURE_RELIEF', score: 2 },
  { technology: 'SUPPORT', score: 3 },
  { technology: 'MOTION_ISOLATION', score: 2 },
  { technology: 'TEMPERATURE_MANAGEMENT', score: -1 },
  { technology: 'COMFORT', score: 2 } 
];

var result = data.filter(function (el) {
  return condition.indexOf(el.technology) < 0;
});

console.log(result);
