In case you want to give programming a try or use it for a future project. The good news is you can quickly learn if you are focused and dedicated. But the question is, which programming language should you try first?
How to choose the right programming language?
Before you choose among the most popular programming languages on the list below, it’s essential to know how to choose the right one for you.
Different programming languages have advantages and disadvantages. But to better understand the differences, let us first classify these programming languages.
Low-level languages directly communicate to the computer processor unit (CPU) to perform basic to complex commands. The syntax of this class of language is generally hard to read, write, and remember since it uses non-English words as codes.
High-level languages, on the other hand, uses human language (most common in English) rather than machine languages; so it’s easier for programmers to read and write codes. This language is then converted using a compiler to translate high-level language into the machine-readable low-level code.
The programming languages in demand this year are generally used for most of the applications and websites you see today. As such, we will focus on high-level languages on this list. Here are just a few of the top programming languages you can learn and use this 2019:
