Package

Every Go program is made up of packages.

Programs start running in package main.

This program is using the packages with import paths "fmt" and "math/rand".

By convention, the package name is the same as the last element of the import path. For instance, the "math/rand" package comprises files that begin with the statement package rand.

Note: The environment in which these programs are executed is deterministic, so each time you run the example program rand.Intn will return the same number. (To see a different number, seed the number generator; see rand.Seed. Time is constant in the playground, so you will need to use something else as the seed.)

main.go
    package main

    import (
        "fmt"
        "math/rand"
    )

    func main() {
        fmt.Println("My favorite number is", rand.Intn(10))
    }

ButtonTest.jsx
function ButtonTest() {
    return (
        <Button onClick={() => alert('omg it worked')} color="secondary">Click Me</Button>
    )
}
const project = 'Docusaurus';

const Greeting = () => <p>Hello {project}!</p>;

render(<Greeting />);
function Clock(props) {
  const [date, setDate] = useState(new Date());
  useEffect(() => {
    const timerID = setInterval(() => tick(), 1000);

    return function cleanup() {
      clearInterval(timerID);
    };
  });

  function tick() {
    setDate(new Date());
  }

  return (
    <div>
      <h2>It is {date.toLocaleTimeString()}.</h2>
    </div>
  );
}
const project = 'Docusaurus';

const Greeting = () => <p>Hello {project}!</p>;

render(<Greeting />);
