sns-react-siema/src/lib/utils/debounce.js

ReactSiema is a lightweight carousel plugin for React. It's a wrapper based on decent library [Siema](https://github.com/pawelgrzybek/siema).

export default (func, wait, immediate) => {
    let timeout;
    return () => {
        let context = this, args = arguments;
        let later = () => {
            timeout = null;
            if (!immediate) func.apply(context, args);
        };
        let callNow = immediate && !timeout;
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
        if (callNow) func.apply(context, args);
    };
};
