1. C++ :
C++ or CPP is a general-purpose statically typed object-oriented programming language. In 1980, C++ was developed by Bjarne Stroustrup at bell laboratories of AT&T (American Telephone & Telegraph) as an extension to the C language. This seed has expanded since then and had become one of the most well-known and used language all over the world. C++ is built for pretty much everything except the web. Primarily it is used for game development and embedded programming. C++ is successfully used by Evernote, LinkedIn, Microsoft, Opera, NASA, Facebook, etc.

Advantages :

  • C++ also has the features like polymorphism, data encapsulation etc.
  • We can also run C programs in C++.
  • Portable
  • Low-level language while also being easier to learn.
  • Has unions and structures
  • Gives the user control over the memory
  • One of the largest community
  • Scalability

Disadvantages :

  • Control over the memory makes the code prone to errors.
  • Memory leakage
  • No garbage memory collector
  • No support for the built-in thread feature
  • In Web, it is hard to debug

2. JavaScript :
JavaScript or JS is a high-level dynamically typed programming language. JavaScript was built for the web, and was initially created to “make the web pages alive”.it came into appearance in 1995 via Netscape .its a high level, interpreted, Scripting language .its used on most websites by an enormous margin, by the analysis of last year 95% of the websites use JavaScript. it’s so popularly used that most web browsers have built-in engines to handle it. Companies using JavaScript are Microsoft, Paypal, Netflix, Groupon, Uber, Facebook, Google, etc.

Advantages :

  • Very fast as it runs on the web browser
  • JIT(just-in-time) compilation allows to directly run code
  • Easy to learn
  • Large community base
  • Inter-operable
  • Versatile
  • Lots of libraries

Disadvantages :

  • Issues with client-side security
  • Code is visible to everyone
  • Small error can take down the whole website
  • Debugging is not easy
  • The continuous conversions of numbers to an integer increase the time needed to run the script and reduce its speed.


Difference between C++ and JavaScript :




01.It is a statically typed language.It is a dynamically typed language.
02.It is considered to be grouped with low level programming language.It is a high level programming language.
03.It was created by Bjarne Stroustrup at bell laboratories of AT&T in 1980.In 1995, JavaScript was introduced by Brendan Eich at Netscape i.
04.It is little challenging to learn for beginners.It is little easy to learn for beginners.
05.C++ is more faster as compared to JavaScript.JavaScript is little slower as compared to C++ programming language.
06.Actually it was built for everything else than web.It has been built for web pages.
07.It is a programming language.It is a scripting language.
08.It is compiled and executed.It is compiled language.
09.It is an object oriented programming language.It is a multiparadigm programming language which supports event-driven, functional.
10.Companies using C++ are Google, Lyft, Twitch, coderus etc.Companies using JavaScript are Microsoft, Paypal, Netflix, Groupon, Uber, Facebook, Google, etc
