What to know before you start programming

I suggest sololearn.com, they consist of great courses where you can learn the most
popular languages right now, including C++, C, HTML5, CSS, and Javascript are few of many If you are getting bored while learning, stop and try creating something with it, if you encouter a error
just go back and look at the examples and keep trying until you get it.

Languages I Suggest

I started with web development, HTML, CSS then Javascript, I am learning JS now after JS
I plan on doing PHP, which looks straightforward but PHP is server-side scripting
