There are plenty of training materials online to start your journey.
But … I strongly recommend starting with the basics and principles first before jumping on core development. This can save you a lot of time in faulty code investigation and prevents unnecessary initial frustration (learning curve).
Btw., I am more like a person who learns from visual sources and I can give your a few tips on what I use for your start:
We are living in a very fast and dynamic world now. The days when software developer could have just a narrow set of skillset are gone and in order to “do good” on the market, everyone must adopt.
It does not have to be a radial adaptation process (phew!) but having a reasonable good knowledge about certain development languages, patterns, frameworks and “way of doing stuff” ala trends is the must.
That is why YOU as a software developer should know these languages at least an intermediate level to be able to code some basics without googling.
Alright, enough of initial sauce of words, let’s get into these three languages according to 2020 Dev survey.
Must languages to learn
1. Believe it or not, the best option for you is Python. I am not going to write what this language is in detail but in brief, this interpreted and high-level and generic-purpose language has become integrated into almost any type of solution you can think of (cross-platform). Well, that is not surprising to me as been with us for almost 3 decades now (1991). What is more interesting in it is the actual philosophy which stands on these points:
3. And probably my favourite one over these two is Go (Golang). Not because of my experience (just started to learn this) but because of what is capable of in very short time (hey I am C# dev, I know what I am talking about!). This would not be my surprise if Go makes its way to the top of the ladder in the next 3 years.
Just remember, that data has been collected from an active society contributing to Stackoverflow. That means that these results do not EXACTLY reflect the market situation globally nor in your region. Always do your homework and look at the different data sources, related to the place you live (and going to be for the next 5 years).
New Zealenders this does not apply for you. You cannot go wrong with these three ones. Just for reference, NZ based company Rocket Lab is constatly hiring Software Engineers with Golang experience https://www.rocketlabusa.com/careers/positions/.
Overall Stackoverflow survey rating
it’s great to have an actual IT pros attending in this survey
Stack overflow holds a big audience
in my opinion, data were collected from younger generation as oppose to older and so segregated datasets might not be in required balance for reports
