Cree un nuevo objeto a partir de una matriz compleja de objetos usando Javascript

Tengo una matriz de objetos y quiero enviar solo los valores de cada objeto dentro de la matriz a un nuevo objeto como un par de valores clave usando Javascript.

p.ej:

 const prices = [ { ticker: 'msft', price: 14.3 }, { ticker: 'msft', price: 10.2 }, { ticker: 'ibm', price: 9.2 }, { ticker: 'amzn', price: 10.2 }, ];

La salida debe ser la siguiente:

 { "msft":[10.2,14.3], "ibm":[9.2], "amzn":[10.2] }

const output = prices.reduce((result, object) => { const key = object.ticker; result[key] = result[key] || []; result[key].push(object.price); return result; }, {})
