Definition of OCaml
OCaml is a general-purpose programming language that provides us object-oriented features, OCaml is open source and free. It comes up with some more features such as pattern matching, exception handling, automatic garbage collection, and many more which we will see in detail in the coming section of the tutorial. Ocaml used applications that majorly focused on programmer analyzer, interpreters, compiler, and the applications which involve automatic theorem provers and symbolic representation as well. IN the coming section of the tutorial we will see its usage in different and benefits of using as well.
Why do we need OCaml?
OCaml stand for objective Caml, also it comes up with many advantages which can add value to the development. In this section, we will see what are the key things and benefits it provides which make it best to use. Let’s take a closer look at some of the points which make it needed, which are as follows;
1. Abstract type: We have seen in many programming languages the concept of abstraction which hides the technical details from the user, so in this, we have some more advantages by this, by the use of Abstract type, we can hide or cover our types in the modules. In OCaml, we have parameterized modules, in general when we do abstract over any expression or any value in programming then we are trying to define a parameterized function. So in OCaml, we can define a module which is representing one set or group of integers here for us, so in OCaml, we can define this set of integers as the parameter so that we can have a set of anything as the parameter.
2. Namespaces: In large applications or large programs we have many conditions where we have the same names so to avoid that condition we can define Namespaces for that. We can ignore or avoid this name collision problem by using or defining functions, types, values, or exceptions in the module, and after that, we force them to use these name define to refer to it.
3. Hiding of information: In OCaml, we can give module a signature by the use of this we can prevent or avoid some names referenced from any outside module. For this, we can define the helper function in OCaml. In short we in OCaml we can restricted our module signature begin referenced from the outside module and provide them more and more restricted signature in OCaml.
4. Multi-paradigm programming language: Also it is multiple paradigm programming which means by the use of it we can classify or divide our programming based on the features they have.
5. Portability: OCaml language is a portable language that comes up with but code interpreter which can be run anywhere with that ANSI C compiler. It will generate a byte code for us we have in other languages and these files can easily be run anywhere and very portable across systems.
6. Development tool: While doing development with OCaml, they provide us very good support with the development tool also. By the OCaml distribution, we can get the basic things like byte-code interpreter, native code compilers, byte code compiler, and top-level interactive. OCaml distribution also provides us good profiler and debugger as well.
How do OCaml works?
As of now we already know that OCaml is a strongly typed language which means all the error can be known at the compile-time only. Also, it does not perform any implicit casting of types for us. IF we want we have to make it manually for us. This language does not do any automatic casting or conversion of the types in short.
Also while working with this language if we want to return something from it then we have to write that expression at the end of the statement, in OCaml, we do not have any return statement for this, automatically the last statement will become the result for us. If we talk about the data types we have in OCaml then below you can see the list of basic data types we have in OCaml and that can be used easily by the developers as well see below;
OCaml also provide us various in built data type which further classified into two groups
1) basic data types: this includes the common data types such as string, character, integers, Boolean and etc.
2) sophisticated data types: this includes stakes, queues, tuple, data stream, and many more
Advantages and Disadvantages
First, we can have a look at the advantages of using this language which are mentioned as follows;
Ocaml programming language, it Is a general-purpose programming language that provides us object-oriented features, also provides good support for exception handling as well. Now, we will see its features in details for better understand;
1) Ocaml provides us native code compiler, apart from its existing compiler it also provides us one additional compiler which helps us to get the machine code for various architectures.
2) Ocaml also provides us automatic memory management, by the use of garbage collector, which is very fast and unobtrusive.
3) It provides us portable bytecode compiler which helps us to create stand-alone applications.
some of the disadvantages of using Ocaml or learning are as follows;
1) It is not so popular like any other programming language, so it can happen you learn it and may not get proper work on it. There are very less article and support for this as of now.
2) We have another point lacking is parallelism and concurrency in this language.
Usage of OCaml
There are many things where we can use this language we will see some area where we can use it efficiently for better results. which are as follows;
3) In computation or symbolic computation
6) theorem provers etc.
As we have discussed in this tutorial why we use it and where we can use it makes it pretty much clear for us to understand it. This language has so many advantages that we have discussed but one thing comes major that it is not very much popular which adds a minus point here.
