const exec = debounce(()=>{
    console.log('time: ' + Date.now());
}, 3000);



function clickme(){
    exec();
}


function debounce(fn,delay){
    let timer = null 
    return function(...args) {
        if(timer){
            clearTimeout(timer);
        }
        timer = setTimeout(()=>{
            fn.call(this, args);
        },delay);
    }
}
