As a programmer, we’re learning lots of technologies. We’re using multiple technologies in the development process. At that time we can’t remember all syntax, methods, functions, or other language-related rules. So, a cheat sheet is there to help us. It’s basically a document in which you can find syntax, methods, and other concepts. Let’s start with one by one.

1. OverAPI.com

overapi.com is a popular website for cheatsheets. You can find many languages such as JavaScript, PHP, Node.js, Python, plus more.

2. Awesome-Cheatsheets

Awesome-Cheatsheets is also a website, where you find cheat sheets. They provide cheat sheets for Node.js, Django, C, C++ etc.


Node is a leader in the asynchronous framework market. The platform now supports a huge portion of startups and businesses that are earning hundreds of millions of dollars in revenue. Thus, it establishes itself as a platform that can sustain a huge load, whilst retaining smooth performance. Node.js was perhaps the biggest revelation of modern server engineering that we saw. By the looks of it, Node isn’t stopping any time soon; it’s the exact opposite. The project continues to push out frequent updates and maintains old releases to support older platforms. …


JavaScript is classy, but how can a machine actually understand the code you’ve written?

Like JavaScript devs, we usually do not have to deal with compilers ourselves. However, it’s really nice to know the basics of a JavaScript engine and see how it handles our personalized JS code and makes it something machine-understood! 🥳

Note: This post is mainly based on the V8 engine used by Node.js and browsers based on Chromium.

In your code, the HTML parser looks for a script tag and its associated source. Now from that source, program/code loaded. It can be from a network, temp storage, or any other service worker. Then the reply is in form of a…


AI & ML has grown over the past few years, which will allow us to get more information on the data collected. We can also implement ML to work as a UX designer, a product designer, and an interaction designer.

Artificial intelligence (AI) and Machine Learning (ML) have been making curls over the years, from the impact of major sectors such as retail, health, and safety. With each passing year, and in the fast-evolving, technology is changing our world in a way that was a fantasy.

For some of the “get started”, it is something to be wary of. A lot of people will see it as a threat to their jobs, and a relentless machine that is all you can do is do what they do, only better, faster, without the need to pay up or go to sleep.

AWS DynamoDB is a cloud-native noSQL primarily key-value database

DynamoDB is a key-value noSQL database created by Amazon. Unlike other products offered by Amazon and other retailers in that it is not just an open source program, like Spark, hosted on retailers. Amazon has written this for their internal needs and is now making it available to their customers.

Let’s define each of those words.

  • DynamoDB is cloud-based because it does not work on buildings or hybrid cloud; only works on Amazon Web Services (AWS). This enables it to scale as needed without requiring a client’s investment in hardware. …

Serverless and cloud computing has seen a major uptake in recent times, becoming industries unto themselves, with AWS Lambda leading the way

AWS Lambda is a serverless computer service or FaaS (Service as a service) provided by AWS. It supports a wide range of possible causes, including incoming HTTP requests, queued messages, customer emails, changes to database records, user affirmation, messages coming to web sockets, patron device sync, and much more. AWS Lambda also helps you focus on your core product and business mindset instead of managing the operating system (OS) access control system, etc.

Because app developers do not combine or distribute server code to control a network socket in AWS Lambda, their applications are serverless. …
