What is a Programming Language?
A programming language is a computer program used to solve problems. They are commands, algorithms or instructions given to a computer to carry out certain computer operations.
Going into the field of software programming is an outstanding stride. Software development is very vast, and there are different types of programming languages associated with each niche in software programming.
To better understand the concept of programming languages, we liken Software development to a university, where the various fields in Software development such as cloud computing, web development, and blockchain technologies are the faculties or departments of the university.
And in turn, the Programming languages are the courses in these various departments. To survive in a particular software development field, one could be required to learn two or more programming languages.
There are many programming languages to learn; keep reading to get the general concept and make a choice.
10 Best programming languages to learn
