    var $search = $('#search');

    $posts.each(function(){

        });

        cache.forEach(function(post){
            var index = 0;

            if (query) {
                index = post.title.indexOf(query);

            }
            var results = document.getElementsByClassName('search-results');
            results.innerHTML = "<li>"+cache.title+"</li>";
            post.element.style.display = index === -1 ? 'none' : '';
        });
    }

   if ('oninput' in $search[0]){
        $search.on('input', filter);
    } else {
        $search.on('keyup', filter);
    }

}());

COPY

Make sure you have jquery installed. If the code interferes with other functions then remove the oninput function and use only $search.on('keyup', filter);

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
