A small example of using destructuring for named function arguments and orderless optional arguments. This allows you to create a single function with different argument options without having to maintain complex argument ordering

destructured arguments

const isFunction = fn => typeof fn === 'function'
const isNumber = n => typeof n === 'number' && !isNaN(n)

function createFunctionPipe({ interval, fn, args = [] } = {}) {  
  if(!isFunction(fn)){
    throw Error('Invalid callback (fn) argument');
  }
  
  if(isNumber(interval)) {
    return setTimeout(() => fn(...args), interval);
  }
  
  return function() {
    return fn(...args.concat(...arguments));
  }
}

createFunctionPipe({
  interval: 300,
  fn : console.log,
  args: [0,9]
});


createFunctionPipe({
  fn : console.log,
  args: [1,2]
})(3,4,5);
