Q:

(`[name="${name}"]`).value) -->what that part of the code says?

const [sobre, nome, titulo] = ['sobre', 'nome', 'titulo'].map(
    name => form.querySelector(`[name="${name}"]`).value);

(`[name="${name}"]`).value)

what that part of the code says ?

A:

It's a string template. Basicaly, it's like concatenating string but directly in the string.
the selector output would be
[name="sobre"]
[name="nome"]
[name="titulo"]

Because we are replace ${name} with the value of the name variable.
if you want a more concrete example, you could simple use the same loop, with a console log.

const [sobre, nome, titulo] = ['sobre', 'nome', 'titulo'].map(
    name => console.log(`[name="${name}"]`));
