Not every case you can replace a looping method for the short one, but if it does then do it.
Instead of:
let names = [‘Amy’, ‘James, ‘David’, ‘John’];
for (let i = 0; i < names.length; i++) {}
Do this:
let names = [‘Amy’, ‘James, ‘David’, ‘John’];
for (let name of names) {}
In case the indexes matter:
for (let [index, name] of names.entries()) {}

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;
}
