- Returns: It returns the concrete type of the specified elements.
Is Julia a functional programming language?
Julia is very much a functional language, and loves being functional. With that, a great example is what I demonstrated in my looping speed test, Julia works really well with functional recursion. Functional recursive loops are my personal favorite appearance-wise to utilize when doing statistical work.
What does colon mean in Julia?
Punctuation
| symbol | meaning |

Is Julia dynamically typed?
Julia is dynamically typed, but in well-written julia code the types can usually be inferred. You often get a major performance enhancement when that is possible.
Is Julia language object oriented?
Julia is not object-oriented in the full sense because you cannot attach methods to Julia’s objects (“types”). The types do seem very similar to objects though. However, since they do not have their own associated methods and there is no inheritance the objects themselves don’t do the acting.
Why is Julia not popular?
The negatives that Julia users report are that it’s too slow to generate a first plot and has slow compile times. Also, there are complaints that packages aren’t mature enough – a key differentiator to the Python ecosystem – and that developers can’t generate self-contained binaries or libraries.
Is R losing to Python?
R can also be used within data science notebooks like Jupyter, but Python is the default mode. DataCamp’s Theuwissen says the Python ecosystem is outgrowing the R ecosystem. Since Microsoft acquired Revolution Analytics in 2015, the number of data science and analytic software vendors focusing on R has shrunk.
Does Julia replace Python?
Even though there are many benefits of using Julia over Python, Python will not disappear anytime soon. Here’s why: Julia is young; Python is mature. Julia was released publicly in 2012 while Python has been around for three decades.
