Drop it

function dropElements(arr, func) {
  //arr 中的每个值，都调用一次func
  [...arr].some(item=> {
    if(func(item))
      return true
    else {
      arr.shift()
      return false
    }
  })
  return arr;
}
dropElements([1, 2, 3], function(n) {return n < 3; });

测试数据：

dropElements([1, 2, 3, 4], function(n) {return n >= 3;}) should return [3, 4]. dropElements([0, 1, 0, 1], function(n) {return n === 1;}) should return [1, 0, 1]. dropElements([1, 2, 3], function(n) {return n > 0;}) should return [1, 2, 3]. dropElements([1, 2, 3, 4], function(n) {return n > 5;}) should return []. dropElements([1, 2, 3, 7, 4], function(n) {return n > 3;}) should return [7, 4]. dropElements([1, 2, 3, 9, 2], function(n) {return n > 2;}) should return [3, 9, 2].
