I need to go through an array of objects and return an array that contains the "taxNumber" ordered by the names. How could I do it?
const paddockManagers =
[ { id: 1, taxNumber: '132254524', name: 'JUAN TAPIA BURGOS' }
, { id: 2, taxNumber: '143618668', name: 'EFRAIN SOTO VERA' }
, { id: 3, taxNumber: '78903228', name: 'CARLOS PEREZ GONZALEZ' }
, { id: 4, taxNumber: '176812737', name: 'ANDRES VIÑALES CIENFUEGOS' }
, { id: 5, taxNumber: '216352696', name: 'OSCAR PEREZ ZUÑIGA' }
, { id: 6, taxNumber: '78684747', name: 'JOAQUIN ANDRADE SANDOVAL' }
]
function listPaddockManagersByName() {
return paddockManagers.map((paddockManager) =>
addockManager.name + paddockManager.taxNumber)
};
Use Array.sort and String.localCompare to sort the array lexographically (by the name property), then map over the result to get the taxNumber property.
const paddockManagers = [
{ id: 1, taxNumber: '132254524', name: 'JUAN TAPIA BURGOS'},
{ id: 2, taxNumber: '143618668', name: 'EFRAIN SOTO VERA'},
{ id: 3, taxNumber: '78903228', name: 'CARLOS PEREZ GONZALEZ'},
{ id: 4, taxNumber: '176812737', name: 'ANDRES VIÑALES CIENFUEGOS'},
{ id: 5, taxNumber: '216352696', name: 'OSCAR PEREZ ZUÑIGA'},
{ id: 6, taxNumber: '78684747', name: 'JOAQUIN ANDRADE SANDOVAL' }
];
const result = paddockManagers.sort((a, b) => a.name.localeCompare(b.name)).map(e => e.taxNumber)
console.log(result);sort method will change your array initial order.
If you want to preserve this initial order, you need to duplicate your array first ( .map() )
const paddockManagers =
[ { id: 1, taxNumber: '132254524', name: 'JUAN TAPIA BURGOS' }
, { id: 2, taxNumber: '143618668', name: 'EFRAIN SOTO VERA' }
, { id: 3, taxNumber: '78903228', name: 'CARLOS PEREZ GONZALEZ' }
, { id: 4, taxNumber: '176812737', name: 'ANDRES VIÑALES CIENFUEGOS' }
, { id: 5, taxNumber: '216352696', name: 'OSCAR PEREZ ZUÑIGA' }
, { id: 6, taxNumber: '78684747', name: 'JOAQUIN ANDRADE SANDOVAL' }
]
const listPaddockManagersByName = arr =>
arr
.map(row=>row)
.sort((a,b)=>a.name.localeCompare(b.name))
.map(({name,taxNumber}) => `${name}, ${taxNumber}`)
let result = listPaddockManagersByName( paddockManagers )
console.log( paddockManagers )
console.log( result ).as-console-wrapper { max-height: 100% !important; top: 0 }
