  "type": "Program",
  "start": 0,
  "end": 26,
  "body": [
    {
      "type": "ExpressionStatement",
      "start": 0,
      "end": 26,
      "expression": {
        "type": "CallExpression",

        "callee": {
          "type": "MemberExpression",
          "start": 0,
          "end": 11,
          "object": {

          }
        ]
      }
    }
  ],
  "sourceType": "module"
}
)

// hello world!

参数选项

options.injectObj: 通过这个对象可以将外部变量注入到内部代码

例子:

import { run } from 'mine-jsjs'
const str = 'hello'
run(`console.log(hello + ' world')`, { hello: str })
// hello world

options.module: 按照module的方式运行code，运行后会返回内部代码export的变量

例子：

import { run } from 'mine-jsjs'
run(`
exports.hello = 'hello'
`)
// { hello: 'hello' }
