TypeScript anonymous function

Question

What is the TypeScript equivalent of this JavaScript?

(function() { 
    /* code here */ 
})();

I have tried this

() => {
    /* code here */
}

But this produces

(function() {
    /* code here */
});

I need the extra set of parenthesis at the end to perform an execution of the anonymous function.

Answer 1

(() => {
    /* code here */
})();

or simply use the JavaScript (which is equally valid TypeScript)

(function() { 
    /* code here */ 
})();

... depending whether you want to capture this using the fat arrow.

Playground.
