Getting Started

How To Install

Run:

npm i --save object-line-finder

Then:

const objectLineFinder = require("object-line-finder");

const example = 
{
  "firstName": "user",
  "lastName": "a",
  "age": 50
}

console.log(objectLineFinder(example, "age")); // [4]

Additional information

This Stackoverflow link talks about how elements of an object are looped in the order they are declared if all the keys are strings. However, keys that are numbers are always first.

Jest somehow adds an additional default key that maps to the entire object. This causes the code to break. A temporary fix is to exclude the default key when doing the checks.

if (key === 'default') { break; }
