Therefore, we are going to cover computer programming languages which are popular and have high demand in the job market. With the bit we would cover, you can then decide which is the right for you to start with. 

Criteria for choosing the best programming language for you

It will be frustrating for anyone without the knowledge of the criteria required for choosing the right programming language. Beyond the technical criteria that are required, it is necessary for aspiring programmers to understand coding takes determination. Furthermore, most in-demand programming languages are harder to learn.

Before we delve into the top traits to have in order to learn to program, you must ask yourself if you are motivated enough.

Here are some of the top key criteria to consider in choosing the best programming language for you.

Technical qualities (use cases)

There are numerous programming languages in the world today. While most are general-purpose languages, they all have use cases unique to their inherent technical capabilities. The choice of a language

It is worth noting that based on the type of application they are been adopted for, each language has its advantages and disadvantages. For example, different languages are best suited for developing a web application compared to a banking/enterprise solution. The programming language that will perfectly code web apps may exhibit flaws for banking and vice versa.

Learning curve (how easy to learn)

For those mulling the question, what coding language should I learn? It is advisable to analyze the potential learning curve adequately. Our learning abilities differ. What can take someone a month to learn can take others several months. However, with a programming language, there are those ranked based on the ease of learning. These options are best to be explored by newcomers.

Another major factor that can wade an influence here is your previous experience. Do you already know a programming language, or are you familiar with the fundamentals of coding such as syntax? These factors can greatly influence how easy it can be for you to learn a new language.
