Difference between C++ and JavaScript

1. C++ :

C++, often known as CPP, is a statically typed object-oriented programming language. Bjarne Stroustrup created C++ in the bell laboratories of AT&T (American Telephone & Telegraph) in 1980 as an extension to the C language. Since then, this seed has grown into one of the most well-known and widely spoken languages in the world. Except for the web, C++ is designed for almost everything. It is primarily used in game creation and embedded programming. C++ is utilised successfully by Evernote, LinkedIn, Microsoft, Opera, NASA, and Facebook, among others.

Advantages :

  • Polymorphism, data encapsulation, and other characteristics are also available in C++.
  • C++ can also run C applications.
  • Portable
  • Low-level language that is also easier to learn.
  • There are unions and structures.
  • Allows the user to manipulate the memory.
  • One of the most populous communities
  • Scalability

Disadvantages :

  • Controlling memory makes the code more prone to faults.
  • Memory leaking
  • There is no garbage memory collector.
  • There is no support for the built-in threading capability.
  • It is difficult to debug web applications.

2. JavaScript :

JavaScript, also known as JS, is a dynamically typed high-level computer language. JavaScript was designed for the web and was originally intended to "bring online pages to life." It first appeared in 1995 via Netscape. It is a high-level, interpreted scripting language that is widely used; according to a recent study, 95% of websites utilise JavaScript. Because it is so widely used, most web browsers include built-in engines to handle it. Microsoft, Paypal, Netflix, Groupon, Uber, Facebook, Google, and other companies use JavaScript.

Advantages :

  • Because it operates in a web browser, it is extremely quick.
  • JIT (just-in-time) compilation enables code to be run directly.
  • Simple to grasp
  • a sizable community base
  • Inter-operable
  • Versatile
  • There are numerous libraries.

Disadvantages :

  • Client-side security issues
  • Everyone can see the code.
  • A minor issue might bring the entire website down.
  • Debugging is a difficult task.
  • The constant conversion of numbers to integers increases the time required to run the script and slows it down.???????
