支持数组通配的路径解析与数据操作

What does the proposed API look like?

1. 路径解析支持数组通配符

   FormPath.parse('foo[].bar'); // segments ['foo', '[]', 'bar'] or ['foo[]', 'bar']

2. 支持数据操作

   
   const source =  { foo: [{ bar: 1 }, { bar: 2 }, { bar: 3 }] };

FormPath.getIn(source, 'foo[]'); // [ { bar: 1 }, { bar: 2 }, { bar: 3 } ] FormPath.getIn(source, 'foo[].bar'); // [1, 2, 3]

FormPath.setIn(source, 'foo[].bar', 0); // { foo: [{ bar: 0 }, { bar: 0 }, { bar: 0 }] }

FormPath.setIn(undefined, 'foo[].bar', 1); // { foo: [] } FormPath.setIn(undefined, 'foo[].bar', [1, 2, 3]); // { foo: [{ bar: 1 }, { bar: 2 }, { bar: 3 }] }

FormPath.setIn(undefined, '[].bar', 1); // [] FormPath.setIn(undefined, '[].bar', [1, 2, 3]); // [{ bar: 1 }, { bar: 2 }, { bar: 3 }]

FormPath.deleteIn(source, '[].bar'); // { foo: [{}, {}, {}] }
