Recursively iterate over an object to return an array of all the paths in the object

object-props-to-array.js

function extractPropsToArray(obj, arr = [], path = "") {
  for (const key in obj) {
    if (Object.hasOwnProperty.call(obj, key)) {
      const element = obj[key];
      const isObject = typeof element === "object";
      if (isObject) {
        const pathname = Boolean(path) ? `${path}.${key}` : `${key}`
        extractPropsToArray(element, arr,pathname )
      } else {
        const pathname = Boolean(path) ? `${path}.${key}` : `${key}`
        arr.push(pathname);
      }
    }
  }
  return arr;
}

/* For an object like 
{
  message: "Businesses gotten successfully",
  data: {
    docs: [
      {
        _id: "64243cebfc3c14b0649693fa",
        name: "New Business ltd",
        createdAt: "2023-03-29T13:28:11.396Z",
        industry: "Salad",
        location: "Netherlands",
        totalTasks: 21,
        totalCompletedTasks: 0,
      },
    ],
    totalDocs: 1,
    page: 1,
    prevPage: null,
    nextPage: null,
    totalPages: 1,
  },
}

we should get the return value
[ 'message',
  'data.docs.0._id',
  'data.docs.0.name',
  'data.docs.0.createdAt',
  'data.docs.0.industry',
  'data.docs.0.location',
  'data.docs.0.totalTasks',
  'data.docs.0.totalCompletedTasks',
  'data.totalDocs',
  'data.page',
  'data.totalPages' ]
