Difference Between JavaScript and C++
In this article, we will learn the difference between JavaScript and C++. JavaScript and C++ are two widely used programming languages, each designed for different purposes and environments. While JavaScript is primarily used for web development, C++ is known for its high-performance applications, including game development and system programming.
The following are the differences between JavaScript and C++
JavaScript is a lightweight, interpreted programming language. It is designed for creating network-centric applications. It is complementary to and integrated with Java. JavaScript is very easy to implement because it is integrated with HTML. It is open and cross-platform.
C++ is a middle-level programming language developed by Bjarne Stroustrup, which started in 1979 at Bell Labs. It runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.C++ is used in system software, game development, embedded systems, and applications requiring efficient memory management.
Nature of the Language:
- JavaScript is a high-level, interpreted scripting language mainly used for web development.
- C++ is a middle-level, compiled programming language used for applications requiring high performance.
Compilation vs. Interpretation:
- C++ code is compiled and then executed.
- JavaScript code is interpreted and executed in real-time by the browser.
Typing System:
- JavaScript is dynamically typed; variables do not require explicit type declarations.
- C++ is statically typed; variable types must be defined during declaration.
In Java, you have to declare the type of the variable with the variable, for example ?
int a; float f;
In JavaScript, you need to only write the variable name, without adding the type. After that, you can assign the value like 5 for int, "amit" for string, etc, for example?
var a; var f;
JavaScript supports Java virtual machine implementation, whereas C++ does not support Java virtual machine implementation. C++ supports procedural and generic programming. JavaScript supports reflective programming.
Use Cases
The following are the use cases of JavaScript and C++?
Feature | JavaScript | C++ |
Web Development | Frontend & Backend | Not typically used |
Game Development | Limited, Web-based games | High-performance games |
System Software | Not used | OS, drivers, compilers |
Performance-Critical Apps | Slower execution | Fast execution, optimized |
