I´m trying to looping through a Json... to get a new var = an array made up of months values [enero,febrero,marzo,etc] but I CANT DO IT, because console keeps telling me : Uncaught ReferenceError: data is not defined.

Json:

"mes": "Enero",
"T. media (C)": 10.5,
"T. min (C)": 6.5,
"T. max (C)": 15.1,
"Precipitacion (mm)": 10.3,
"Humedad (%)": 74,
"Dias Luviosos (dias)": 10,
"Horas de Sol (h)": 6.1
},
etc etc etc

this is the code for main.js


async function todo() {
const consulta = await fetch("https://raw.githubusercontent.com/br444ndy/c8/main/datos.json");
const data = await consulta.json();
console.log(data);
}

var meses = [];

data.forEach((m) => {
meses.push(m.mes());
});

console.log(meses);
