function debounce(callback, delay = 300) {
  let timeout;

  return (...args) => {
    clearTimeout(timeout);

    timeout = setTimeout(() => {
      callback(...args);
    }, delay);
  };
}

// Example: avoid running a search request on every keystroke
const search = debounce((query) => {
  console.log("Searching for:", query);
}, 500);

search("javascript");
search("javascript debounce");
search("javascript debounce function");

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;
}
