Sé que hay muchas preguntas similares, sin embargo, no pude encontrar ninguna solución hasta ahora. Así que tengo este objeto

let data = [ { NAMEK: ... coordinates: {lat: ..., lng: ...} }, { NAMEK: ... coordinates: {lat: ..., lng: ...} } ]¿Cómo podría lograr esto con la desestructuración?
¿O hay alguna manera mucho mejor?
Un Array.map() bastante sencillo en input.features junto con algo de desestructuración debería darle el resultado que desea:
