export { zh2jp, zht2jp, zhs2jp, zhs2zht, zht2zhs, cjk2zhs, jp2zhs, jp2zht, cjk2zht, cjk2jp, IOptions } from './core';

Expected behavior:

Object.defineProperty(exports, "__esModule", { value: true });
var core_1 = require("./core");
Object.defineProperty(exports, "zh2jp", { enumerable: true, get: function () { return core_1.zh2jp; } });
Object.defineProperty(exports, "zht2jp", { enumerable: true, get: function () { return core_1.zht2jp; } });
Object.defineProperty(exports, "zhs2jp", { enumerable: true, get: function () { return core_1.zhs2jp; } });
Object.defineProperty(exports, "zhs2zht", { enumerable: true, get: function () { return core_1.zhs2zht; } });
Object.defineProperty(exports, "zht2zhs", { enumerable: true, get: function () { return core_1.zht2zhs; } });
Object.defineProperty(exports, "cjk2zhs", { enumerable: true, get: function () { return core_1.cjk2zhs; } });
Object.defineProperty(exports, "jp2zhs", { enumerable: true, get: function () { return core_1.jp2zhs; } });
Object.defineProperty(exports, "jp2zht", { enumerable: true, get: function () { return core_1.jp2zht; } });
Object.defineProperty(exports, "cjk2zht", { enumerable: true, get: function () { return core_1.cjk2zht; } });
Object.defineProperty(exports, "cjk2jp", { enumerable: true, get: function () { return core_1.cjk2jp; } });

Actual behavior:

the (last) will emit wrong js code in Version 4.0.0-dev.20200601

this bug happen in super low chance

Related Issues:

Start with the linked TypeScript files, especially packages/cjk-conv/lib/jp/index.ts and its re-export from ./core, then reproduce the emitted JavaScript with the reported compiler versions. Compare the output for the IOptions interface against the expected output; done means the multi re-export no longer emits an incorrect runtime export.
