使用示例

• 拒绝检查、首个匹配与顺序处理：使用真实清单表达多项检查和枚举分发；单个普通判断仍可直接使用 if。

一个明确的拒绝

入门 · Node.js

TypeScript

import { Support } from '@jangts/agent-core';
const input = '你好';
Support.breakWhile(!input.trim(), '问题不能为空');
console.log(input);

JavaScript

import { Support } from '@jangts/agent-core';
const input = '你好';
Support.breakWhile(!input.trim(), '问题不能为空');
console.log(input);

有依赖关系的检查按序求值

  { occur: () => !('name' in (input as object)), error: '缺少 name' },
]);
console.log(input);

JavaScript

import { Support } from '@jangts/agent-core';
const input = { name: 'Ivan' };
Support.breakWhile([
