Node.js VS Deno: Will Deno replace Node.js?

 Once Deno released there were so many questions and speculations related to Deno and Node.js, one of them was is Deno going to replace node.js?

I think Node.js is pretty much mature and well-established technology. Node.js is also incredibly supported by companies and the community. So for sure, Node.js will be around for a while and Deno is not going to replace it overnight.

Since Deno is like a replacement for Node.js, Let's look at some of the similarities between them.

  • Both Deno and Node.js are developed upon the Chromium V8 Engine.
  • Both are built to develop server-side applications.

Let's dig into the differences between them:

  • Node.js is written in C++ and JavaScript. Deno is written in Rust and TypeScript
  • Node.js has a package manager called npm. Deno doesn’t have a package manager and it lets you import modules directly via URL.
  • Node uses the CommonJS syntax for importing packages deno uses modern ECMAScript features in all its API and standard library, while Node.js uses a callbacks-based standard library and has no plans to upgrade it.. Deno uses ES Modules, the official way.
  • Deno offers a sandbox security layer through permissions. A program can only access the permissions set to the executable as flags by the user. A Node.js program can access anything the user can access.

Track stock market information right in your Terminal.

     Introduction: As a developer, I love working with the terminal. The plain, simple, and in my opinion the best way to interact with the computer (also it makes you look geeky). I spent most of my time in the terminal. By now you must have guessed I am a huge fan of the terminal and terminal-based applications. Recently I developed an interest in stock markets and started tracking the stock markets. Since I love working with the terminal I decided to build a terminal oriented application that can help me to track the stock market.

Free to use tools for maintaining your OpenSource projects

In this post, we will talk about how to effectively maintain your OpenSource projects using tools/softwares which are free to use for OpenSource and the public repositories. Over time, when the project grows you, need to set up a few tools which can help you maintain the project and automate the trivial tasks. 1. Setup CI/CD Having an OpenSource project to which you might b e  contributing just as a hobby, but doesn’t mean you don’t need to set up CI/CD pipeline. You don’t need to expend a single dime on servers or need to use cloud services to run your CI/CD. There are a lot of CI/CD tools available free for open source projects and public repositories. One such tool is  Travis CI  which you can use for setting up CI/CD for your project. Travis CI Travis CI You can run test cases and deploy code to your servers. Travis CI works great and easy to set up the CI/CD pipeline. 2. Code Analysis and Code Quality Maintaining code quality as the project grows can be very hard and time-consumi

Why I switched to Brave browser from Google Chrome.

  I have used Google Chrome for the last 5–6 years, Chrome was the perfect browser and it has many features like syncing everything across the platform and devices, bookmarks, history, lots of extensions, password manager, auto-complete, developer options to name a few. All of these in with just a Google Id. Google ecosystem is very rich and useful. So why I decided to switch to  Brave  browser after giving it a trial for a month. Although chrome has everything, there were few issues that led me to hunt for a new browser and finally switched to Brave. Why Brave? 1. Chrome hogs the RAM “Aw ,  Snap! Google Chrome ran out of memory while trying to display this webpage.” I am sure you might have seen this message. This message appears when chrome has eaten all of the available RAM memory. I understand the reason behind Chrome using a lot of memory because of its architecture. It runs all the tabs in a separate process so that it can provide isolation.
