What is Deno?

Deno is a simple, modern, and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.

If you are familiar with Node.js, the server-side JavaScript framework, then Deno should be a no brainer for you. Deno is also a server-side JavaScript framework except that it has been improved in many ways.

The list of features that Deno offers are:

  • Built around modern JavaScript features
  • It has an extensive standard library
  • It has first-class TypeScript support. This brings a huge advantage in many different ways such as you don’t have to separately compile TypeScript, it’s automatically done by Deno.
  • Secure by default. No file, network, or environment access, unless explicitly enabled.
  • It has no package manager
  • It has a first-class await
  • It as a built-in testing facility
  • It aims to be browser-compatible as much as it can, for example by providing a built-in fetch and the global window object
  • Ships only a single executable file.

After using Deno, Node.js looks like old school. Especially because the Node.js API is callback-based, as it was written way before promises and async/await. There’s no change in place for that in Node, as such a change would be monumental, so we’re stuck to callbacks or to promisifying API calls. Node.js is awesome and will continue to be the de facto standard in the JavaScript world.

Thanks for reading. If you have some feedback, please reach out to me on Twitter or Github.

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. Inspir e d by  wttr.in  I build  terminal-stocks  which can provide the stock's current prices, historical prices, and global market summary. How to use terminal-stocks terminal-stocks  is available and can be used without installation. Get the current price of the stock. curl terminal-stocks.dev/ITC.NS Current price of stocks You need to provide the ticker of the stock and terminal-stocks will give you the price information of the stock.  terminal-st

Terraform: Understanding Desired & Current State

In this post, we will learn in detail what is terraform desired and current state. Terraform’s responsibility is to create/update/destroy infrastructure resources to match the desired state as described in the configuration. Desired State: For example: If our desired state is as below resource "aws_instance" "myec2" { ami = "ami-0ca285d4c2cda3300" instance_type = "t2.medium" } This should result in an AWS EC2 t2.medium instance. The code you saw above is the desired state that we want. Current State: The current state is the actual state of a resource that is deployed. For example: If our desired state is as below resource "aws_instance" "myec2" { ami = "ami-0ca285d4c2cda3300" instance_type = "t2.medium" } our desired state is t2.medium instance but let’s say the current instance running is t2.micro. So it means our desired state and the current state is not matching. Try it out
