我尝试使用reduce从数组创建字典。然而，当使用reduce从数组创建字典时，我遇到了一个flow错误属性，该属性在object literal [1]中丢失。这对所有三个键'A'，' B'，和'C'都发生了。

const foo = [
    'A',
    'B',
    'C',
  ];

  const bar = foo.reduce((acc, curr) => {
 
    // the actual code will do some logic on the string value in foo
    // but for the test just create a dictionary of the key to itself as value

    acc[curr] = curr;
    return acc;
  }, {});
