split-key

Supercharge your JSON objects by mapping multiple keys to one value

Install

npm install --save split-key

Usage

const splitKey = require('split-key');

splitKey({
  'primary, secondary': {
    color: 'red'
  }
});
//=> {
//  primary: {
//    color: 'red'
//  },
//  secondary: {
//    color: 'red'
//  }
// }

Use the included fromArray function if you have flat input of a single array. This function also performs with more speed than fromArray(). The downside is that it is more verbose for anything beyond a single value:

const arr = ['primary', 'secondary', 'tertiary'];
splitKey.fromArray(arr, {
  color: 'purple'
});
//=> {
//  primary: {
//    color: 'red'
//  },
//  secondary: {
//    color: 'red'
//  }
// }
