了解什么时候需要格式化 JSON、如何检查嵌套 payload，以及如何在提升可读性的同时避免改变数据。

理解常见 JSON 解析错误，包括缺少逗号、尾随逗号、未转义引号和无效复制片段。

Use Base64 encoding and decoding for safe inspection of text payloads, documentation examples, and lightweight developer workflows.

Decode JWT header and payload data for debugging while keeping the signature verification boundary explicit.

Test regex patterns against realistic sample text, understand flags, and avoid shipping brittle text matching logic.

Read five-part cron expressions, review common schedules, and document scheduled jobs with fewer timing mistakes.
