Posted 2021-03-14 qjb2404

const data = {
  portLand: ‘78/50‘,
  Dublin: ‘88/52‘,
  Lima: ‘58/40‘
}

Object.defineProperty(data, ‘Lima‘, {
  enumerable: false,
  writable: false
})

console.log(Object.keys(data))
console.log(Object.getOwnPropertyDescriptors(data))
console.log(Object.getOwnPropertyDescriptor(data, ‘Lima‘))
