Serverless Technology Part-1

Image
  Serverless technology , also known as serverless computing, is a cloud computing model in which cloud providers dynamically allocate and manage the infrastructure required to run applications. In a serverless architecture, developers can focus on writing and deploying code without worrying about the underlying infrastructure. Traditionally, in a server-based model, developers have to provision and manage servers to run their applications. They need to consider factors such as capacity planning, scaling, and server maintenance. However, with serverless technology, these responsibilities are abstracted away, and developers can concentrate on writing business logic. The key features of serverless technology include: Event-driven execution:  Serverless platforms execute functions in response to specific events, such as HTTP requests, database updates, or message queue triggers. This event-driven approach allows applications to scale automatically and handle bursts of traffic eff...

Details in JavaScript Array Methods with Examples

Image
  Why we need JavaScript array methods. JavaScript arrays are data structures that allow you to store multiple values in a single variable. JavaScript arrays are commonly used to hold lists of data such as numbers, strings, objects, or other arrays. We need JavaScript array methods because they allow us to perform various operations on arrays easily and efficiently. These methods can help us to add or remove elements from an array, sort an array, filter an array, create a new array from an existing array, and more. By using these methods, we can write more concise and readable code, which can save time and reduce the likelihood of errors. Most uncommon array methods with examples More or less, we use JavaScript array methods now a days, but most are the common once. We are actually not so much aware others important methods. Today I am trying to introduce those and definitely sure this will be helpful to write more concise and readable code than you before did. 1.Array.from() Array...

Most powerful/popular JavaScript frameworks

Image
  JavaScript frameworks are tools that simplify web development by providing ready-to-use features, libraries, and components. They help developers to write code faster, with fewer bugs, and create more efficient web applications. Here are some of the most powerful JavaScript frameworks: React - React is a popular and widely used front-end framework developed by Facebook. It uses a component-based approach to build interactive user interfaces for web applications. Angular - Angular is a TypeScript-based framework developed by Google. It is used for building complex web applications with features such as data binding, dependency injection, and routing. Vue - Vue.js is a progressive JavaScript framework used for building user interfaces and single-page applications. It is known for its simplicity and ease of use. Ember - Ember.js is a powerful and opinionated framework used for building scalable web applications. It provides features such as two-way data binding, a powerful routing s...
