Certification is another factor to consider when choosing the best coding course. It can be very beneficial to have evidence of your study that you can take to interviews or add to your LinkedIn profile. Whether you need certification to prove your new skills might depend on where you want to work since qualifications are more likely to be requested if you're applying for an in-house position.
Most courses will offer some sort of validation to certify that you've completed their syllabus, but, how much that is worth can depend on how recognised the course provider is, which is why we've been sure to include some highly recognised online coding course providers in our list above.
