如何访问Promise的<state>和<value>属性？

Question

我有一个承诺，我必须得到内部的价值，但它的def balanced_parens(string, parens_map) # where we throw opening parens opening_parens = [] i = 0 while i < string.length # if current index is opening paren add to array if parens_map.keys.include? string[i] opening_parens << string[i] # if current index is closing paren, remove last item from opening_array elsif parens_map.values.include? string[i] popped_paren = opening_parens.pop # checking that closing parens at current index is a match for last open parens in opening_array return false if string[i] != parens_map[popped_paren] end i += 1 end # if opening_parens array is empty, all parens have been matched (&& value = true) opening_parens.empty? end 和<value>属性似乎无法通过常规手段访问。我以前从未见过具有<state>外观的属性，所以我认为这可能是线索。

如何访问这些属性？

编辑：我找到了一种方法，但它不是重复问题的答案

将代码粘贴到控制台的代码：
