The task we are going to perform in this article is ‘set object property in an array true/false whether the id matches with any if from another array of objects in JavaScript’. Before we jump into the article let’s have a glance at the object and array in JavaScript. An object in JavaScript is a separate entity having properties and a type. JavaScript objects have properties that specify their attributes. Multiple values can be kept in a single variable by using arrays. Compare that to a variable that only has room for one value. Each item in an array has ... Read More
In this article we are going to find out whetehr it is possibleto change the value of the function parameter in JavaScript. A function accepts a certain values as parameters an later while calling this function we need to pass values for these parameters as arguments. Typically a function definition contains the name of the function, parameters (optional) and the body of the function.Syntax Following is the syntax for function parameter − function Name(paramet1, paramet2, paramet3, paramet4) { // Statements } Yes, it is possible to change the value of the function parameter in JavaScript. ...

Introduction Jupyter notebooks are useful for writing, testing, and debugging code. TensorFlow is a machine learning framework that can be used with Jupyter notebooks. In this article, we will explore how to use Docker to start a TensorFlow Jupyter notebook, which will allow us to take advantage of the benefits of both of these tools. Prerequisites Before getting started, you will need to have Docker and Docker Compose installed on your machine. You can check if it is installed using the following commands − $ docker --version $ docker-compose --version You can follow the installation instructions for your ... Read More
Introduction As developers, we frequently need to incorporate private data into our applications, including passwords, API keys, and database credentials. Not only is it unsafe to hardcode these variables into our code or configuration files, but it can also be challenging to manage and change them when necessary. Using environment variables, which let us keep sensitive data apart from our codebase and configuration files, is one method to manage secret values. In this article, we'll look at how to maintain secret values using docker-compose v3.1 and inject them as environment variables into our containers. Prerequisites To follow along with this ...

In this article, we will discuss various approaches and techniques for improving Docker image size with layers, including multi-stage builds, using minimal base images, and using base images with pre-installed packages or pre-built binaries. By following these best practices, we can create smaller and more efficient Docker images that are optimized for performance and scalability. The size of Docker images with layers can be improved using a variety of methods as given below. Methods Using minimal base images Using base images with pre-built binaries Using multi-stage builds Using base images with pre-installed packages Let us discuss these methods ... Read More
Introduction By using containerization, we can quickly set up and configure our deployment environments, which helps us save time and resources. With the goal of "write once, deploy anywhere" in mind, containerization can help us streamline the process of deploying modern applications, which can be complex. Finding the layers and layer sizes for Docker images In this article, we will explore how to find the layers and layer sizes for each Docker image. This can be useful for identifying large layers that may be contributing to the overall size of the image, and for determining which layers can be removed ... Read More
Introduction Docker is a powerful tool that allows developers to build, ship, and run applications inside containers. Containers are small, independent executable packages that contain all the components - code, libraries, dependencies, and runtime - that an application requires to function. One of the key features of Docker is the ability to manage and monitor the processes running inside containers. In this article, we will explore how to find Docker container processes and how to use different methods to view and manage them. Prerequisites You will need Docker installed on your computer in order to follow along with this guide. ... Read More
Docker is a widely used tool for developing and managing containerized applications. It enables programmers to combine their applications with their dependencies into small, portable containers that are simple to set up and use on any platform. Directly mounting Network File System (NFS) shares or volumes inside a container using Docker Compose v3 is one practical Docker capability. In this article, we will explore how to use Docker Compose v3 to directly mount an NFS share or volume in a container. Method to directly mount NFS share/volume in the container using Docker Compose v3 Here are some important terms and ... Read More
In this article, we will learn how to write a swift program to find the prime numbers from the array. Prime numbers are those numbers that are only divisible by 1 and itself. Or we can say prime number have only two factors that are 1 and the number itself. For example, 1, 2, 7, 3, 11, 31, etc. So to find the prime numbers from the given array, we individually check each element of the given array is prime or not. Algorithm Step 1 − Create a function. Step 2 − Check if the number is greater than ... Read More
In this article, we will learn how to write a swift program to remove all ‘nil’ elements from the array. Till now we all know that an array can store elements of a single data type. But Swift array can also hold elements of multiple data types. To store multiple data types in the array we use [Any], where [Any] specifies that the address can hold elements of any data types. Similarly an array also contain nil value. Here we use the following methods to remove nil elements from the array. Using compactMap() function Using filter() function ... Read More
