Hello Abir. Welcome to Careers360. You can look for the laptops with the following specifications:-

i3 7th gen processor or more

minimum 4 gb ram

1 TB HDD

These are the only basic requirements that you will need in your laptop. Since programming is not concerned with high end graphics, so don’t look for laptops that have high graphic cards and resolutions. These minimum requirements are sufficient for programming. Hope this answer helps. All the best.
