How to run the same snippet multiple times without page reload?

Question

I am playing with JavaScript in "Sources" tab in Google Chrome. I have created this snippet:

const sayHello = () => console.log("Hello");
sayHello();

The problem is - I can run it only one time. If I clicked on "Run" button again - an error will be displayed in "Console":

Uncaught SyntaxError: Identifier 'sayHello' has already been declared at :1:1

Of course I can Refresh the page each time before I ran the Snippet - but it's get tedious and I would much prefer another solution. Basically I want to write multi-line JS code and then execute it and see all its output in console.

Try to use 'var' instead of 'const'.

You cannot rewrite constants, they are read only.
