Coding is a skill that is increasing in it’s importance. Schools are spending time teaching children to code preparing them for the future. Society needs people who can code to create the next technology.
Another reason is that it is fun. It uses your brain power to solve problems or create solutions. It is logical which appeals to many people but it is used in the creative arts, education, transport, medicine, business etc. There is no part of society that it doesn’t touch.
Whatever the reason you find to code, have a go. It isn’t easy but neither is it as hard as you might think and there is a huge community out there to help if you get stuck.
