// It seems like something happened to these strings
// Can you figure out how to clear up the chaos?
// Write a function that joins these strings together such that they form the following words:
// 'Javascript', 'Countryside', and 'Downtown'
// You might want to apply basic JS string methods such as replace(), split(), slice() etc

function myFunction (a, b) {

 	b = b.split('').reverse().join	('')
	return a.concat(b).replace(/[^a-zA-Z ]/g, '')

}

myFunction('java', 'tpi%rcs')   // returns 'javascript'
myFunction('c%ountry', 'edis')	// returns 'countryside'
myFunction('down', 'nw%ot')		// returns 'downtown'

How to Get the Domain From A URL Using Javascript

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;
}
