Jest is a library that allows you to test JavaScript code, and it is widely used for testing React applications. It is fast, easy to use, and maintained by Facebook. In this article, we will explore the different features of Jest and how to write effective tests using it. Introduction to Jest Jest is an open-source project maintained by Facebook. It is designed for testing JavaScript code and is particularly well-suited for testing React applications....
Test your React components using Jest and react-testing-library to ensure their functionality and performance. In this blog post, we will walk you through the process of creating and running tests for your React components. Getting Started To start testing your React components, it is recommended to use snapshot testing. This technique allows you to test components in isolation, similar to unit testing for classes. If you have already created a React app using create-react-app, you will have Jest installed, which is the testing package we will be using....

Arduino Create is an incredible cloud editor designed to streamline your Arduino programming experience. With this powerful tool, you can write and compile code directly in your web browser, eliminating the need to install any software on your computer. The only requirement is to install a plugin that allows the platform to recognize the Arduino board connected to your computer. Once that’s done, everything else is automatically updated, making it incredibly convenient and time-efficient for getting started with Arduino....
I recently got my hands on the Arduino MKR WiFi 1010 board and I must say, it’s a game-changer for IoT enthusiasts. This board is the first of its kind to have built-in WiFi and Bluetooth connectivity. In this blog post, I want to give you an overview of this impressive board and compare it to the popular Arduino Uno, which is often the go-to choice for beginners. Form Factor Let’s start with the appearance of the Arduino MKR WiFi 1010....
The Arduino Uno Rev 3 board is the go-to version for prototyping projects. Countless tutorials use this board as their reference, making it a popular choice among developers. Key Features Form factor and size compatible with Arduino 101, Arduino Zero, Arduino Yún, Arduino Leonardo, Arduino Uno Wifi rev 2, and Arduino Ethernet. Equipped with an 8-bit microcontroller, the ATmega328P, featuring 32 KB of Flash memory, 2 KB of SRAM, and 1 KB of EEPROM....
The Arduino Uno is the go-to microcontroller board for many developers. As the reference version of Arduino, it sets the standard for performance and functionality. The latest official Arduino device, the Arduino Uno WiFi rev 2, takes the Uno to the next level. With the same form factor and size as other Arduino boards like the Arduino 101, Arduino Zero, and Arduino Leonardo, the Uno WiFi rev 2 offers enhanced capabilities....
Arrays are a fundamental data structure in programming languages, including JavaScript. In lower-level languages like C, arrays represent a set of contiguous cells in computer memory. However, in JavaScript, arrays work differently as we are abstracted away from the memory management. In JavaScript, arrays can store any kind of data, allowing for mixing different types within the same array. Initialization of an array can be done using either const myArray = [] or const myArray = new Array()....
Estimating the time required to build software projects is often a challenging task. Over the past decade, I have been asked this question countless times, and I must admit that giving an accurate estimation is an elusive feat. Clients and stakeholders frequently inquire about the timeline for implementing a particular feature or completing a project. But the reality is, estimating software development time is akin to making a bet or taking a leap of faith....
MongoDB is a database system that is responsible for storing and retrieving information in an application. As a NoSQL database, MongoDB does not use the SQL language for querying data. Key Characteristics of MongoDB MongoDB is a JavaScript-friendly database, providing a JavaScript API for creating databases and collections of objects called “documents”. It is schemaless, meaning that there is no need to pre-define a structure for the data before storing it....
