Hello, a common question that pops-up all the time is “how to handle imposter syndrome”. Especially as junior-developer you might feel overhelmed at times. Let me tell you that this feeling is completley normal and everyone feels the same.
Software Engineering is a difficult field that moves at a fast pace. Nobody can know everything there is to know about development. Its plain impossible.
Even experienced developers are confronted with situations where they have to you a new paradigm or framework. Its your job to learn about these unknowns.
Feeling imposter syndrome therefore means growing your skills.
Just in time learning is real
Learning stuff as you go is a real and common practice in software enginneering. Is not by accident that stackoverflow is the most important website for developers of all kind. Just in time learning is a valuable skill own its own that every software developer needs to fullfill his job.
Accept that you will never know everything
Accepting that you will never know everything there is to know can be encouraging. Stay humble and accept that you will forever be a trainee in the field of software engineering.
It gets better with experience
Even tho imposter syndrome never really gets a way, it will get better as you gain more experienced and are more comfortable in your situation. So dont be discouraged, there is a small light at the end of the darkness that is imposter syndrome.
