立即调用命名函数-Babel vs Typescript问题

Question

当我使用打字稿来编译此功能时，它可以正常工作。但是，当我将babel与typescript插件一起使用时，它说checkForRenewedToken is not defined

let data;
let newToken;
await new Promise(resolve => {
(async function checkForRenewedToken() {
        newToken = getToken()
        if (!newToken) {
            setTimeout(checkForRenewedToken, 1000);  <--- checkForRenewedToken is not defined
        } else {
            data = await doCall(newToken);
            resolve(data);
        }
    })();
});
return data;

要使babel开心，我必须这样更改它：

let data;
let newToken;
await new Promise(resolve => {
    const checkForRenewedToken = async () => {
        newToken = getToken()
        if (!newToken) {
            setTimeout(function () {
                checkForRenewedToken(); <--- now it's happy
            }, 1500);
        } else {
            data = await doCall(newToken);
            resolve(data);
        }
    };
    checkForRenewedToken();
});
return data;

为什么打字稿能够编译该行，但是带有@babel/preset-typescript插件的babel无法编译？
