What is the best way to utilize criteria in TypeScript?

I'm curious about how to get these if and else conditions to function properly. It's frustrating that it's not working as expected. Any assistance would be greatly appreciated.

if (element > 9) {
    Array.from(counter).forEach((element: HTMLElement, index) => {
            console.log(index, element);
            element.innerText = (index + 1).toString();
        });
}else if (element <= 9) {
    Array.from(counter).forEach((element: HTMLElement, index) => {
                console.log(index, element);
                element.innerText = '0' + (index + 1).toString();
            });
}

As far as I am aware, TypeScript does not contain the operator <==. It is recommended to use <= instead. If you require strict type checking, consider casting the variable named element to an integer beforehand.
