Answer 1

This will give the desired result

var no_nuts = _.filter(products,function(item) {
         return !item.containsNuts;
       });

var no_mushroom = _.reject(no_nuts,function(item) {
        return _.any(item.ingredients,function(item1) {
            return item1 === "mushrooms"
        }); 
     });

console.log(no_mushroom);

reject() does the opposite of filter(), and any() is equivalent to some method of arrays which returns true when any of the element in the array when passed through a callback returns true.
