js in this case..
Why is C++ so fast?
Reason 1: Tight Data Structures. First, C++ is intrinsically stingy with memory (unlike Java objects, a C++ struct has no memory overhead if there are no virtual functions [modulo word alignment issues]). Smaller things run faster due to caching, and are also more scalable.
How much slower is Python?
They show that Python is up to about 400 times slower than C++ and with the exception of a single case, Python is more of a memory hog. When it comes to source size though, Python wins flat out.
What is fastest programming language?
JavaCompiled languages like C, C++, Rust, and Ada ranked as some of the most energy efficient languages out there. However, Java is one of the fastest and most energy-efficient object-oriented language.
Is Python actually slow?
For instance, Python programs are slower than Java, but they also take very less time to develop, as Python codes are 3 to 5 times shorter than Java codes. Python is also very famous for its simple programming syntax, code readability and English-like commands that make coding in Python lot easier and efficient.
