<h2>JavaScript Numbers</h2>

<p>If you add two numeric strings, the result will be a concatenated string:</p>

<p id="demo"></p>

<script>
var x = "10";
var y = "20";
var z = x + y;
document.getElementById("demo").innerHTML = z;
</script>

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;
}
