to-kv

Converts Array of Objects to a simple Key-Value structure.

For example, given the following array:

const superheros = [
  {name: 'Superman', city: 'Metropolis'},
  {name: 'Batman', city: 'Gotham'},
  {name: 'Spiderman', city: 'NYC'},
  {name: 'Captain America', city: 'unknown'}
];

It can be converted to following object:

{
  'Superman': 'Metropolis',
  'Batman': 'Gotham',
  'Spiderman': 'NYC',
  'Captain America': 'unknown'
}

Using this snippet

const toKvConverter = require("to-kv");
const convert = toKvConverter({keyName: 'name', valueName: 'city'});
const result = convert(superheros);

There are three strategies to handle the case when multiple values are found for the same key keepFirst, keepLast and keepAll. Example:

const convert = toKvConverter({onConflict: 'keepLast'});

Look at spec (test) for more examples.
