I have a simple website with two HTML pages each with a linked Javascript code:

Front Page:

<!DOCTYPE html>
<html>
  <body>
    <script src="primeiraPagina.js"></script>
  </body>
</html>

Second Page:

<!DOCTYPE html>
<html>
  <body>
    <script src="segundaPagina.js"></script>
  </body>
</html>

How I can transfer data from one script file to the other, for example transfer the value of a variable from primeiraPagina.js to the secondPagina.js, without the use of frameworks.

You can do this in two ways, the first one can be using the sessionStorage. That saves data in the brownser and expire next to it. 

//Utilize esse comando para setar o valor na primeira
sessionStorage.setItem('dados', 1);

and

//Utilizar esse comando para recuperar os dados na segunda
sessionStorage.getItem('dados');

You can also pass this data through the url as described in this post

    Right around the time I mentioned it, you changed to sessionStorage, hahaha. Just the one I was going to suggest +1
