Hey @superoo7,

it's good to see that some devs here are using const and quite a good code style, I appreciate that. Mostly I see bad formatted code and tons of bad practices happening around here.

I also like that you provided tests, I just want to give you a small example on how to remove the hardcoded test1, test2, test3 declarations plus the 5 lines for the expectations:

const testCases = [
  {
    test: base('something @superoo7 something'),
    expect: base(`<span>something ${aTag} something</span>`),
  },
  {
    test: base('something [@superoo7 something'),
    expect: base(`<span>something [${aTag} something</span>`),
  },
  ...
];

testCases.forEach(({ test, expect }) => {
  expect(HtmlReady(test).html).toEqual(expect)
});

And you can remove the console.log inside the testcase.

What do you think about it? :)
