javascript - ES模块旧语法(ES modules old syntax)

I'm learning allowSyntheticDefaultImports and esModuleInterop in TypeScript config, and I just realized the existence of ESM old syntax like the following.

(我正在TypeScript配置中学习allowSyntheticDefaultImports和esModuleInterop ，并且我刚刚意识到ESM旧语法的存在，如下所示。)

export bar = xxx;

When/Who did start to support these syntax?
