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' }
