C Language

C language is primarily used for system software programming and is the Operating Systems’ lingua franca. C has impacted all programming languages, particularly C++and Objective-C. So, if you have a good understanding of C, it will perhaps be easier for you to choose other famous programming languages. Since the code of the C is more complex to do simple tasks, it is a tough language to start with and you may need to put some extra efforts on it. But C language understanding will absolutely help you as a programmer in future. C is an excellent option to become a brilliant developer and a master coder.

As we know that C is one of the widely used programming languages. As it is stated by a renewed programmer Joel Spolsky, “C is to programming as learning basic anatomy is to a medical doctor”. C is a “machine level” programming language that allows you to learn the ways program interrelates with the hardware and learn the programming fundamentals. Learning this language would allow you to have a good understanding of memory management, debugging programs, and the functions of the computer that you may not able to do in other higher-level programming languages such as Java. So, you can say that C is a very versatile language that keeps prepping you to efficiently code for other programming languages. You better call it a “grandfather” of other higher-level programming languages, such as C#, Java, and JavaScript. Some pros and cons of C and C++ languages are as follow:

Pros:

PHP language is first made for creating personal web pages that’s why it first stands for Personal Home Page but later it is changed to Hypertext Preprocessor. It one of the most famous and widely used languages. It is also among the easiest programming language to learn. It is a server-side programming language that executes on a server. Furthermore, it is beneficial for making HTML web pages. The major reason why PHP is a widespread programming language is that it is free, cheap, and easier to use. So, if you are a beginner then PHP is the best option for you to start with. You can also use the PHP language to develop web applications. It is also a good choice if you want to create content management systems such as WordPress.

PHP is a popular backend programming language. However, PHP is getting a tough competition from JavaScript and Python, although there are many PHP developers are in the market but the demand for more developers is still very high. PHP programming is quite a good language to learn if you want to do banked programming. Here are some major pros and cons of PHP language.

JavaScript

JavaScript is broadly used for designing interactive frontend apps. It is primarily a “frontend” language. For example, if you click on a button that opens a popup, this logic is applied through JavaScript, it is mainly a client-side scripting language that is widely used for developing front-end applications. JavaScript is well-suited transversely for all browsers and is can create more interactive web applications, frequently by using the libraries, for example, front-end frameworks and jQuery like Ember.js, AngularJS, etc.

Nowadays, many organizations, mainly startups, are using NodeJS that is a JavaScript run-time setting. Node.js allows the developer to use JavaScript language for server-side scripting—executing server-side scripts to make content for dynamic websites before the page is directed to the web browser of the user. Henceforth now with JavaScript, a programming language can be used for client-side and server-side scripts. You must consider learning JavaScript language if you want to get a tech job in a company of your choice. 

Pros:

  • Client-side JavaScript is faster as it runs directly in the web browser as there is no need for compilation
  • It is highly versatile
  • It reduced demand for website server because it is a client-side language
  • It offers numerous add-ons, for example, Greasemonkey, for functionality extending
  • You will get a lot of resources and support for the mammoth community
  • Remarkably works well with other languages
  • Offers a richer website interface
  • It is the web-based programming language
  • Time to time updates through the ECMA plan
  • Basic implementation
  • Used for creating a wide and diversified range of apps

Cons:

  • It allows only single inheritance
  • Absence of equivalent or copy technique
  • Might be differently interpreted by all browsers
  • The code executes on the user machine, a lot of people disable JavaScript because of the fear of malicious action exploitation.
