Convert Object Reference to String dot Notation JavaScript

getStringDotRefFromObject.js

function getStringDotRefFromObject(obj, arr = [], objPath = '') {
  const isObject = typeof obj === 'object' && !Array.isArray(obj) && obj !== null;
  if (!isObject) return objPath;
  return Object.keys(obj).reduce((acc, curr) => {
    const path = obj[curr];
    return acc.concat(
      // eslint-disable-next-line prefer-template
      getStringDotRefFromObject(path, arr, `${objPath ? objPath + '.' : ''}${curr}`)
    );
  }, []);
}
const result = getStringDotRefFromObject({
    this: {
        is: {
            nested: {
                object: ''
            }

// Output - ["this.is.nested.object", "and.this", "and.is.a", "and.is.sibling"]
