Trying to learn how to use classes with javascript, not sure how to initialize class correctly -


not sure why construction of class not working, maybe i'm calling function in wrong way? here code: 

  function zeros(bits, pattern) {     this.bits = bits;     this.pattern = pattern;   };    zeros.prototype.short = function() {     return this.bits.match(this.pattern)[0].length;   };    heyjude = zeros('1100110011001100000011000000111111001100111111001111110000000000000011001111110011111100111111000000110011001111110000001111110011001100000011', /([0]).*?\1+/);   console.log(heyjude.short());

call via new keyword:

var heyjude = new zeros('...');
