Custom debounce mechanism

Implement your own debounce function that limits the frequency of calls to the passed function.

const requestUrl = (url) => {
    console.log(`fetching ${url}...`);
}

function debounce(func, delay) {
    // implement debounce logic
}

const debouncedFetch = debounce(requestUrl, 300);

debouncedFetch(1);
debouncedFetch(2);
debouncedFetch(3);
debouncedFetch(4);
debouncedFetch(5);
