Take a nested Javascript object and flatten it, or unflatten an object with delimited keys.

var flatten = require('flat')

 

flatten({

    key1: {

        keyA: 'valueI'

    },

    key2: {

        keyB: 'valueII'

    },

    key3: { a: { b: { c: 2 } } }

})

 

// {

//   'key1.keyA': 'valueI',

//   'key2.keyB': 'valueII',

//   'key3.a.b.c': 2

// }
