function contador(n) {
return n.filter(n => n.color === 'rojo')
.filter(n => `${n.name}`.includes('n'))
.filter(n => `${n.name}`.includes('N'))
.filter(n => `${n.name}`.includes('a'))
.filter(n => `${n.name}`.includes('A'))

}

console.log(contador(ovejas))

Answer 1

It's not getting a a match and returning an empty array.
The filter is looking for name with ALL 4 letters in it.

this matches any of the letter for example.

const ovejas = [
{ name: 'Noa', color: 'azul' },
{ name: 'Euge', color: 'rojo' },
{ name: 'Navidad', color: 'rojo' },
{ name: 'Ki Na Ma', color: 'rojo'},
{ name: 'AAAAAaaaaa', color: 'rojo' },
{ name: 'Nnnnnnnn', color: 'rojo'}
]

function contador(n) {
return n.filter(n => (n.color === 'rojo' & (n.name.includes("n") | n.name.includes("N") | n.name.includes("a")) | n.name.includes("A")))

}

console.log(contador(ovejas))
