Is there a way to filter an array of objects by a particular value that could be in any property?

Let\'s say I have this object:

var x = [
    {

    var arrOfObj = []; // objects you're sifting
    var prop = 'whatever';
    
    var matches = arrOfObj.filter(obj => Object.keys(obj).some(k => obj[k] === prop));
    

    You want a combination of Array.prototype.filter and Array.prototype.some which returns a boolean if any of the elements of the array match the condition, it also stops iterating the array (in this case the keys of each object) as soon as it finds a match. If you need cross-browser support (and for some reason aren't using babel) the ES 5 version of the above is

    var arrOfObj = []; // objects you're sifting
    var prop = 'whatever';
    
    var matches = arrOfObj.filter(function(obj) { 
      return Object.keys(obj).some(function(k) { 
        return obj[k] === prop; 
      });
    });
