海外TECH	DEV Community	[JavaScript] 7 OOP fundamentals you will need!	https://dev.to/yumatsushima07/javascript-7-oop-fundamentals-you-will-need-4hk8	JavaScript OOP fundamentals you will need Object Oriented Programming is one of the most popular ways in programming Before OOP s list of instructions will be executed one by one But in OOP s we are dealing with Objects and how those objects interact with one another JavaScript supports Object Oriented Programming but not in the same way as other OOP languages C PHP Java etc do The main difference between JavaScript and the other languages is that there are no Classes in JavaScript whereas Classes are very important for creating objects However there are ways through which we can simulate the Class concept in JavaScript Another important difference is Data Hiding There is no access specifier like public private and protected in JavaScript but we can simulate the concept using the variable scope in functions Object Oriented Programming Concepts Object Class Constructor Inheritance Encapsulation Abstraction Polymorphism Preparing the workspaceCreate a new file oops html and write this code on it We will write all our JavaScript code on this file lt html gt lt head gt lt title gt JavaScript OOP fundamentals you will need lt title gt lt head gt lt body gt lt script type text javascript gt Write your code here lt script gt lt body gt lt html gt ObjectAny real time entity is considered as an Object Every Object will have some properties and functions For example consider a person as an object then he will have properties like name age etc and functions such as walk talk eat think etc now let us see how to create objects in JavaScript As mentioned previously there are so many ways to create objects in JavaScript like Creating Object through literalvar obj Creating with Object createvar obj Object create null Creating using new keywordfunction Person var obj new Person We can use any of the above ways to create Object ClassAs I said earlier there are no classes in JavaScript as it is Prototype based language But we can simulate the class concept using JavaScript functions function Person Properties this name Ben this age functions this sayHi function return this name Says Hi Creating person instancevar p new Person alert p sayHi ConstructorActually Constructor is a concept that comes under Classes The constructor is used to assign values to the properties of the Class while creating an object using the new operator In above code we have used name and age as properties for Person class now we will assign values while creating new objects for Person class as below function Person name age Assigning values through constructor this name name this age age functions this sayHi function return this name Says Hi Creating person instancevar p new Person Ben alert p sayHi Creating Second person instancevar p new Person Mel alert p sayHi InheritanceInheritance is a process of getting the properties and function of one class to other class For example let s consider Student Class here the Student also has the properties of name and age which have been used in Person class So it s much better to acquiring the properties of the Person instead of re creating the properties Now let s see how we can do the inheritance concept in JavaScript function Student Prototype based InhertanceStudent prototype new Person Inhertance throught Object createStudent prototype Object create Person var stobj new Student alert stobj sayHi We can do inheritance in above two ways EncapsulationBefore going on to Encapsulation and Abstraction first we need to know what Data Hiding is and how can we achieve it in JavaScript Date hiding is protecting the data from accessing it outside the scope For example In Person class we have Date of Birth DOB properties which should be protected Let s see how to do it function Person this is private variable var dob public properties and functions return age name Ben getDob function return dob var pobj new Person this will get undefined because it is private to Personconsole log pobj dob Will get dob value we using public funtion to get private dataconsole log pobj getDob Wrapping up of public and private data into a single data unit is called Encapsulation The above example is the one that best suites Encapsulation AbstractionAbstraction means hiding the inner implementation details and showing only outer details To understand Abstraction we need to understand Abstract and Interface concepts from Java But we don t have any direct Abstract or Interface in JS Ok now in order to understand abstraction in JavaScript lets takes an example from JavaScript library Jquery In Jquery we will use ele to select select an element with id ele on a web page Actually this code calls negative JavaScript codedocument getElementById ele But we don t need to know that we can happy use the ele without knowing the inner details of the implementation PolymorphismThe word Polymorphism in OOPs means having more than one form In JavaScript an Object Property Method can have more than one form Polymorphism is a very cool feature for dynamic binding or late binding function Person this sayHI function This will create Student Classfunction Student Student prototype new Person Student prototype sayHI function l return Hi I am a Student This will create Teacher Objectfunction Teacher Teacher prototype new Person Teacher prototype sayHI function return Hi I am a Teacher var sObj new Student This will check if the student object is instance of Person or not if not it won t execute our alert code if sObj instanceof Person alert Hurry JavaScript supports OOps ConclusionJavaScript supports Object Oriented Programming OOP Concepts But it may not be the direct way We need to create some simulation for some concepts Credits Yuma Tsushima Yuma Tsushima Readme file Welcome to Yuma Tsushima s Github page Visitor count About

海外TECH	DEV Community	Hands-On Demo With Persistent Data	https://dev.to/noviicee/hands-on-demo-with-persistent-data-1noc	Hands On Demo With Persistent DataThis is a simple and beginner friendly demo to analyze and visualize the data on running containers and where actually the data on the running containers goWe first need to create an image in order to build it and run it It can be any simple image If you are new to Docker and Docker Images you can refer to here for the meanwhile and use the files provided if you face issues in creating a docker image or writing a docker file Now the motto is to check where does the data go after a running container is killed Note I am on Ubuntu The source code for the files that I am using is hereHere we will be covering three cases mysql no mount no volume gt data is lost after killing the containermysql mount                     gt data is kept in the local filemysql volume                    gt data is reserved in the volumeOpen up your terminal and navigate to your working directory i e the folder where a Dockerfile exists so you can run it No mount No volumeExpected Data is lost after killing the containerExecution Run the following command in your terminal docker run d e MYSQL ALLOW EMPTY PASSWORD true mysqlAs we can see the necessary files are being downloaded and the image is getting build Next we need to get the container id of the running container Use docker ps to list all the running containers on your system Here I just have a single container so the output shows the id of a single running container Now that we have our container up and running we can run the following command in order to attach the image to the container docker exec it CONTAINER ID mysqlOnce we are into mysql we can create a database and list it by using create database DB NAME show databases exitNow you will see that a database is created Inside mysql you can type c to clear out the inputs and exit in order to exit from mysql To check whether the database is actually created or not just ls a in your working directory and it will show you your created database Next for checking where does the data go we need to delete the container Use the container id by executing docker ps and kill the running container by executing docker kill CONTAINER ID The container is now killed This can also be verified by executing docker ps on the terminal which shows that no container is up at the current moment Now if you execute ls a in your working directory you will not be able to see the database or any other file that you might have created Hence by using No mount No volume all the data is lost after killing the container MountExpected Data is kept inside of the local folder Execution Run the following command in your terminal docker run d e MYSQL ALLOW EMPTY PASSWORD true v pwd mysql data var lib mysql mysqlNext step is the same we need to get the container id of the running container Use docker ps to list all the running containers on your system Now that our container is up and running we can run the following command in order to attach the image to the database docker exec it CONTAINER ID mysqlBasically the tag it is used frequently to tag images in docker Once we are into mysql we can create a database and list the database by using create database DB NAME show databases exitTo check whether the database is actually created or not just ls a in your working directory and it will show you your created database In order to check for the data we delete the container Use the container id by executing docker ps and kill the running container by executing docker kill CONTAINER ID The container is now killed This can be verified by executing docker ps on the terminal which shows that no container is up at the current moment The full flow can be seen in the snippet below Now if you execute ls a in your working directory you will notice that the created database still exits in the local folder Hence by using Mount the data is kept in the local folder even after the container has been killed VolumeExpected Data is preserved inside the volume Execution Run the following command in your terminal docker run d e MYSQL ALLOW EMPTY PASSWORD true v mysql data var lib mysql mysql in order to start up and run the container The next steps are the same as the above two that is to get the container id of the running container using docker ps and then attach to the database using the command docker exec it CONTAINER ID mysql Now that we are into mysql we can create a database and list the database by using create database DB NAME show databases exitAnd the database is created You can type c to clear out the inputs inside mysql and exit in order to exit from mysql Now we want to check for the data existence so we delete the container Use the container id by using docker ps and kill the running container by executing docker kill CONTAINER ID The container is now killed This can be verified by executing docker ps on the terminal which shows that no container is up at the current moment Now if you will want to check for the data in the volume By simply typing volume on the terminal we will see that there are a bunch of options provided for us in order to help use the volume command One of those is the volume ls This command lists all the volumes present on our local machine We just execute volume ls on the terminal In the output we can see that our created database mysql data still exists even after deleting the container Another command that can be used here is the volume inspect VOLUME NAMEOn executing the above command it will display the details on the particular volume It can be seen in the snippet below Hence by using Volume we can see that the data is kept preserved in the volume even after the container has been killed This was pretty much for analyzing and getting a basic idea of the persistent data on running containers If you are new to the topic you can refer to gt Where does the data goNew to Docker and Containers Refer to gt Beginner s guide to DockerSome additional resources for help Inspect Docker VolumeDigital Ocean on Docker Volumes
