// let-- scope function --

} 
// const -- meaning constant it cant change
const bubbles = {x:100, y:200};
// can't change the value of bubble
const bubbles= "hello world" // can't redeclare bubbles
    //  but you can change the value of x and y

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;
}
