Convert script

import fs from 'fs';
import path from 'path';

import { typeofJsonc } from '../src/index';

const text = fs.readFileSync(path.resolve('./demo/test'), {
    encoding: 'utf-8',
});

console.log(
    typeofJsonc(text, 'Response', {
        prefix: 'I',
        rootFlags: 1,
        disallowComments: false,
        addExport: true,

    /**  aaa  */
    barr: string[];
    /**  this is name  */
    name: string;
    /**  this is demo  */
    demo: IDemo;
    /**  this is arr  */
    arr: (IArr | number)[];
    a: string;
    b: string[];
}

/**  this is arr  */
export interface IArr {
    age: number;
}

export interface IDemo {
    hello: string;

onName	(name: string) => string	(name: string) => ${prefix}${name}	Custom naming If this option set prefix will not work
addExport	boolean	false	Add export keywords, when set true rootFlags set will not work
rootFlags	number	0	Identifiers are e.g. legal variable names. They may not be reserved words None = 0 Module = 1 InAmbientNamespace = 2
disallowComments	boolean	true	Whether to prohibit the generation of comments
