Modern browsers support:

the class keyword for inheritance without prototype

`${string} templates`
``` for concise string manipulation
- [`async/await` keywords](https://caniuse.com/#feat=async-functions) for asynchronous code (inside functions)
- and more!

In [44]:

class Adder {
    add(a, b) {
        document.write(
            `🐍 says <i>${a} plussss ${b} issss ${a + b}</i><br/>`
        )
        return a + b;
    }
}
this.Adder = Adder

Out[44]:

class Adder {
    add(a, b) {
        document.write(
            `🐍 says <i>${a} plussss ${b} issss ${a + b}</i><br/>`
        )
        return a + b;
    }
}

In [45]:

let it = new this.Adder();
it.add(1, 1)
