javascript - Min of a couple of values which must not be 0 -

i need minimum of a, b, c , d. when 1 or more of them 0 fall out of comparison. solve if/else cascade kind of ugly. there cleaner way solve this? math.min alone doesn't work because result in 0 when ever 1 of variables 0.

can put them in array , drop 0 in array? there math.min arrays?

bestprice: ember.computed('a', 'b', 'c', 'd', function() {   var = this.get('a');   var b = this.get('b');   var c = this.get('c');   var d = this.get('d');    return math.min(a, b, c, d); }), 

example:

• a = 0
• b = 10
• c = 20
• d = 30

bestprice: 10

how this?

prices: ember.computed.collect('a', 'b', 'c', 'd'),  bestprice: ember.computed('prices', function() {   var nonzero = this.get('prices').filter(function (x) { return x > 0; });   return math.min.apply(null, nonzero); }),
