What will happen to the asynchronous function, if we redefine it with a synchronous function and call the previous version?

Question

I have a function:

var myFunc = async function() { await fetch... ... };

What happens to this function if you override it like this:

 var alias = myFunc; myFunc = function() { alias.call(this); ... };

Will the asynchronous part (await) continue in the first variant of the function after calling alias.call (this)?

it will be executed, but you will not receive the result, since it is asynchronous and you exit the function (stack) before the result of the asynchronous function (promise) returns.
