And here is a tip for this code line: We can use the common function `zrUtil.isArray` to judge if it is an array. Sure, it needs to be imported from 'zrender/src/core/util' like this `import * as zrUtil from 'zrender/src/core/util'` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
