Here i have an array, im trying to get a value from it, but it returns undefined, i don't know why.
var datos = [
[['Español'][89,76,90,87]],
[['Desarrollo Web'][94,91,90,96]],
[['Matemáitca'][79,83,84,82]],
[['Inglés'][87,89,93,92]],
[['Programación'][75,73,77,71]],
[['Seguridad Informática'][79,83,92,85]],
[['Análisis de datos'][72,71,75,73]],
[['Ineligencia Artificial'][80,83,80,81]],
[['Desarrollo de Video Juegos'][88,92,94,93]],
[['Desarrollo de aplicaciones'][92,95,96,94]]
];
console.log(datos[2][1][3]);You are missing the commas between your arrays:
var datos = [
[['Español'],[89,76,90,87]],
[['Desarrollo Web'],[94,91,90,96]],
[['Matemáitca'],[79,83,84,82]],
[['Inglés'],[87,89,93,92]],
[['Programación'],[75,73,77,71]],
[['Seguridad Informática'],[79,83,92,85]],
[['Análisis de datos'],[72,71,75,73]],
[['Ineligencia Artificial'],[80,83,80,81]],
[['Desarrollo de Video Juegos'],[88,92,94,93]],
[['Desarrollo de aplicaciones'],[92,95,96,94]]
];
console.log(datos[2][1][3]);
