javascript获取数组中的最大数与最小数

最小数

Array.prototype.min = function(){

  var min = this[0];

  var len = this.length;

  for(var i=1; i

    if(this[i] < min){

      min = this[i];

    }

  }

  return min;

}

console.log([78,99,51,63,25,1].min());

//最大值

Array.prototype.max = function(){

  var max = this[0];

  var len = this.length;

  for(var i=1; i

    if(this[i] > max){

      max = this[i];

    }

  }

  return max;

}

console.log([78,09,348,51,1,9].max());
