Invoking a self-executing anonymous function using requestAnimationFrame

Recently, I developed a basic 2D-tile-renderer using JavaScript and decided to convert it to TypeScript. The process went smoothly, with the only challenge being when I tried to call window.requestAnimationFrame with a callback function.

Eventually, I was able to get it working correctly, but I noticed that my implementation deviated from typical TypeScript practices:

        // ... some initialization code above

        var mapper = this;
        (function animloop() {
            window.requestAnimationFrame(animloop);
            mapper.draw();
        })();

To avoid using 'this' within the anonymous function, I had to store it in an auxiliary variable.

I attempted to utilize a TypeScript lambda ( => ), but ran into difficulties understanding the parameter required by the requestAnimationFrame method.

Do you have any recommendations or suggestions for improving my approach?

Here is a way to accomplish the task:

const loopAnimation = () => 
{
    window.requestAnimationFrame(loopAnimation);
    this.display();
}

loopAnimation();
