How to save JSON data to the hard drive? (or access them with javascript)

I'm working on an application to study the syntax of languages used on the web (html, css, javascript and etc ...) through a question and answer mini-game, but my problem has been how to save that data .

The method I learned is this below:

/* coloque os dados em um array */

var dados = ["mizuk","programação","animes"];

/* guarde os dados recebidos no navegador */

localStorage.setItem("user",JSON.stringify(dados));

/* passe os dados para um novo array */

var user = JSON.parse(localStorage.getItem("user"));

/* imprima no console os dados recebidos */

console.log(" nome: " + user[0] + "\n trabalha com: " 
   + user[1] + "\n e gosta de: " + user[2]);

The problem with this is that in this way the data is saved only in the browser and if I wanted to take that application to another place (my cell phone for example), I would not be able to.

Does anyone know a way to save this data locally or simply access them on the "server" via javascript? (so I can put the questions as JSON files in a folder, and then access with javascript)

Move array item to the last position! Unrecognized keyword "as"

You can use the following function:

var dados = ["mizuk","programação","animes"];

function baixarArquivo(name) {
    var link = document.createElement('a');
    link.href = 'data:application/octet-stream;charset=utf-8,' + JSON.stringify(dados);
    link.download = name;
    link.click();
}

<a onclick="baixarArquivo('arquivo.json')">Download</a>

This function will:

create a link
Set the address as the file you want save
Set a name for the file to be saved
automatically click on the link

This way the file is automatically saved
