Given an object 'fakeObj'; loop though all the properties of 'fakeObj' object and add them into an array. If there's a nested object, it should be removed from its parent object and added to the array directly. So, basically, all objects should be detached and made stand-alone in the final array, regardless of their position in the given object …

objects2array.js

// example object
const fakeObj = {
	key1: {
		prop1: true,
		prop2: 34,
		prop3: 'Hello',
		prop4: [],
	},
	key2: {
		prop1: true,
		prop2: {
			subprop1: [],
			subprop2: 234,
			subprop3: {
				a: [],
				b: false,
			},
		},
		prop3: 'Hello',
		prop4: [],
	},
	key3: {
		prop1: true,
		prop2: 34,
		prop3: 'Hello',
		prop4: [],
	},
};

// function to return the final array of standalone objects
function mergeObjectsToArray(object) {
  // array of standalone objects
	const arr = [];

  // go through the passed object
  // check if properties are objects
  // detach them and add them directly in the target array, 'arr'
	validateAndAddObj(object, arr);
  
  // return array of standalone objects
	return arr;
}

function validateAndAddObj(object, targetArray) {
	// for every first-level property
	for (const prop in object) {
		// object to keep track of element
		const element = {};

		// check if property is indeed a property of object
		if (Object.hasOwnProperty.call(object, prop)) {
			for (const subProp in object[prop]) {
				// check if the property is a reference to an object; not an array
				if ( !(typeof object[prop][subProp] === 'object' && !Array.isArray(object[prop][subProp]) ) ) {
					// if yes, run though the object again
					validateAndAddObj(object[prop][subProp]);
				} else {
					// if it's not an object, add it as a property to tracking object, 'element'
					element[subProp] = object[prop][subProp];
					targetArray.push(element);
					break;
				}
			}
		}
	}
}

module.exports.mergeObjectsToArray = mergeObjectsToArray;
module.exports.validateAndAddObj = validateAndAddObj;

Oh okay. It helps, a lot. I'm grateful.

I'm very gratefulful..
Thanks
