Code

/** @type {function(string): void} */
const func = (value) => {
    // ...
}

// Following line should raise an error as 'func' invocation
// is missing required parameter, but it doesn't happen.
func();

Expected behavior:
An error Expected 1 argument, but got 0. should be thrown.

Actual behavior:
No error is thrown. TypeScript allows to invoke former function without passing arguments to it.

Probably due to #13905. @mhegazy
