There are several features that make it a better choice over other programming languages, especially for scientific and technical computing. Performance Julia is designed to be a high-performance language, with a speed that is comparable to that of C or Fortran. Its just-in-time (JIT) compilation allows for fast execution times, while its type system and…

Sometimes you need a function that will help you to aggregate or combine severable iterables in one go. When we read the official Python documentation it states that using zip ” Iterates over several iterables in parallel, producing tuples with an item from each one.” So what does that actually mean? Well in essence essentially…
To start off passing by reference basically means that you are telling the program you have written to pass a variable to a function. When passing arguments to a function, it is important to understand the meanings first. As a result, when you pass by reference to a function, the variable data gets processed and…
