So this is a thread that will guide upcoming developers on the best part to follow when kick-starting their career in any part of programming.

My number one advice is this;

Do not start with any programming language without knowing the area of specialization for easy learning and motivation

More top notch advice will follow suite in this thread.
Remember to follow up.

In Programming we have

Web Development for creating of Websites

App Development for creating of Apps

Software Development for creating of Software

Game Development for Creating of games.

Ensure you know what you are going for and research properly the programming languages that will be involved.

People think coding is difficult.

Quest:
How best can a beginner understand any code?

Ans.
As a beginner, find out the programming language that has that code.

Find out the basic syntax of that programming language.

Find out the function/role of each lines of code you see.

if you want to make it fast as a web developer, keep your hands busy, go for personal projects.
