Need suggestion on coding practices on the concept "Do Not Repeat Yourself"

Any of those help If you really want to get rid of the duplication you could add the count to the enum and interate over all enum values.
But I wouldn't see your code as a violation of the DRY principle as you only have one method and the calls all have different arguments. The code is very readable as it is.

Any of those help I really don't know it this question fits stackoverflow and so sorry if it doesn't. I will really appreciate it if you let me know where should I ask such Qs. ,
How much should I...
code :
int main(int argc,char*argv[]){
int a=atoi(argv[1]);
int b=atoi(argv[2]);
int main(int argc, char *argv[])
    int a = atoi(argv[1]);
    int b = atoi(argv[2]);
    printf("%d + %d = %d\n", a, b, a+b);
    return 0;

To fix this issue Python doesn't support source files encoded with with a fixed-width multi-byte codec such as UTF-16 or UTF-32.
Your file is encoded as UTF-16 Little Endian, which means the file starts with a Byte Order Mark; the first two bytes in the file are (hex) FF and FE. Python trips over the first byte.

Is there a way to refactor this Promises calls into a "best coding practices" version?

wish help you to fix your issue My code works fine, I just want to continue solving this search feature with good coding practices. I feel like I am repeating the same code too many times. I have two different types of objects "programs" and "rentals" if user selected one of both in the search menu I want to search My DB only for the specified object, however if he selects both or neither I want to execute both search functions. In order to achieve this I have a conditional if which checks for those search options, if only one is selected I will execute the respective find() on the respective Schema, , Can be something like this:
code :
if(!queryObj.title) return; // just exit from the function or return representation of an empty result

queryObj.title = queryObj.title.trim();
const titleSplited = queryObj.title.split(' ');//transform it to an array

if(titleSplited.length <= 0) return; // same as above

// define the holder for search operations
const searchPromises = {};

if(!queryObj.selectedSearchObjectType || queryObj.selectedSearchObjectType.indexOf("rentals") > -1)
  searchPromises.rentals = Promise.all(titleSplited.map((value) =>
    getRentalsByQuery({title: { $regex: new RegExp('\\b' + value.toLowerCase() + '\\b', 'i') } } )

if(!queryObj.selectedSearchObjectType || queryObj.selectedSearchObjectType.indexOf("programs") > -1)
  searchPromises.programs = Promise.all(titleSplited.map((value) =>
    getProgramsByQuery({title: { $regex: new RegExp('\\b' + value.toLowerCase() + '\\b', 'i') } } )

if (searchPromises.rentals) {
  searchResults.rentals = searchResults.rentals.concat(await searchPromises.rentals);

if (searchPromises.programs) {
  searchResults.programs = searchResults.programs.concat(await searchPromises.programs);

// Filter results code ...
// .........................
// End of Function
const RENTALS = 'rentals';
const PROGRAMS = 'programs';

const searchFns = {
  [RENTALS]: (value) => getRentalsByQuery({title: { $regex: new RegExp('\\b' + value.toLowerCase() + '\\b', 'i') } } ),
  [PROGRAMS]: (value) => getProgramsByQuery({title: { $regex: new RegExp('\\b' + value.toLowerCase() + '\\b', 'i') } } )

if(!queryObj.title) return; // just exit from the function or return representation of an empty result

queryObj.title = queryObj.title.trim();
const titleSplited = queryObj.title.split(' ');//transform it to an array

if(titleSplited.length <= 0) return; // same as above

// define the holder for search operations
const searchPromises = {};
const searchTypes = [RENTALS, PROGRAMS];

searchTypes.forEach((type) => {
  if(!queryObj.selectedSearchObjectType || queryObj.selectedSearchObjectType.indexOf(type) > -1)
    searchPromises[type] = Promise.all(titleSplited.map(searchFns[type]));

// iterate over created promises
for (let type in searchPromises) {
  searchResults[type] = searchResults[type].concat(await searchPromises[type])

// Filter results code ...
// .........................
// End of Function

fixed the issue. Will look into that further Your goal is to impress interviewers.
They are looking for people who can work in teams and can make reusable code, which can be handed over to colleagues when needing to be switched to a different topic to work on.
