When you’re starting to learn to program, the first question you might ask yourself is, What programming language should I know? There’s no one language that’s best for beginners or is a must-know when you’re first getting started.
At its most basic level, a programming language is a set of rules for giving computers instructions. These instructions can range from simple commands like addition or subtraction to more complex tasks like building a website or creating a video game. And each programming language will have an advantage depending on which of those things you want to do.
So, you see, which language is best for you is difficult to answer because it depends on your goals and experience. This post will discuss the steps you need to take to choose the correct programming language.
There are many different programming languages, and it can be tough to decide which one to learn first. When choosing a programming language, it’s essential to consider your goals and what you want to do with it.
Take an hour or two and imagine what kind of apps you want to develop, what company you want to work for, what conferences you want to present at, and your goals.
Write them down. Walk away from it and come back later. Are those still the ones you want? If not, update the list. Once you know what you want, then you can move on to choosing a programming language.
For example, if you aim to get a job at a specific company, find out what languages they use and learn those. You can usually find this information on the language’s website. Every language has galleries of apps built with its language. And most of them usually list which big companies use their language.
Once you’ve considered your goals, you can start looking at specific languages and decide which one is the best fit for you. There are plenty of resources available online, so don’t be afraid to do some research before making your decision.
To get you started, I’ve described some of the more popular languages and given you a rundown of each one’s uses so that you can start there.
Another research tool is to watch some videos of people programming in these languages. And be sure to take some notes on how each one feels so you can come back to them later.
One of the best ways to narrow down your choices is to ask for advice from other programmers doing what you want to do. Message boards, communities, and Discord servers are great places to find active participants in these programming communities.
Do you have friends or family who are programmers? Seek out their advice. They may be the best resource as they know you, your interests, and your temperament best.
Once you’ve narrowed the field down to two or three languages, start by reading guides and tutorials, watching videos, and trying out small code samples for each language.
You can find all of these resources online for free. Review the basics. Take notes on how each one feels to you and what people are doing with it.
Don’t get bogged down in details or get discouraged if you don’t understand everything at first. The goal is to find a language that feels comfortable for you and that you can learn quickly.
Once you’ve gotten a feel for your shortlist of languages, it’s time to choose. Review your notes and goals and make a decision. However, don’t get too caught up in selecting the “right” language. I’ve learned at least a dozen languages over the years. Your first language won’t be your last.
The final step is to find resources to help you learn your chosen language. Again, I would recommend starting with an online course or tutorial.
There are plenty of free resources available, as well as paid ones. It’s up to you to decide what works best for you.
I will say that you need to persevere and don’t give up—learning to program is challenging but rewarding. The key is to get a solid understanding of your first language to develop projects with it for your portfolio and learn the basics of programming that will apply to your second, third, and nth language.
So, now that you know how to choose a programming language to learn, let’s look at some popular options that you can consider.
