  Introduction JavaScript Object Notation (JSON) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. JSON is widely used in web applications to transmit data between a server and a client. In the process of data exchange, JSON strings often contain escape sequences to ensure that special characters are correctly interpreted. Unescaping JSON involves converting these escape sequences back to their original characters. This article delves into the concept of JSON unescaping , its importance, and how to handle it in various programming languages. What is JSON Unescaping? JSON escape sequences are used to represent special characters within strings. Common escape sequences include \" for double quotes, \\ for backslashes, and \n for new lines. When JSON data is serialized, these characters are escaped to ensure the integrity of the data structure. Unescaping JSON refers to the process of converting th...

  In the world of computer science and data transmission, encoding and decoding are fundamental concepts. One of the most commonly used encoding schemes is Base64. This encoding method is widely used in various applications, from email encoding and web data transfer to encoding binary data for storage. So let's explore more in detail about Base64 decoding, exploring its purpose, how it works, with some practical real life examples. What is Base64 ? Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format, using a set of 64 characters - uppercase and lowercase letters, digits, and symbols. The purpose of using Base64 is to ensure that data remains intact and is not modified during transport. This is particularly useful when transmitting data over media that are designed to handle text, such as email or HTTP. Encoding binary data into ASCII characters helps to prevent data corruption during transmission. For example, consider the binary sequenc...

  HTTP status codes are an essential part of web communication. They provide information about the outcome of a request made to a server. Whether you're a seasoned developer or a student just starting out, understanding these codes can significantly enhance your ability to debug and optimize web applications. This blog will break down the most common HTTP status codes that one generally encounters, explain their meanings and how to handle them. What is HTTP ? HTTP stands for Hypertext Transfer Protocol. It is the foundation of data communication on the World Wide Web. HTTP is an application layer protocol that specifies how clients (such as web browsers) request resources such as web pages or files from servers, and how servers respond to those requests. It is a : - Stateless Protocol : Each request from a client to a server is independent and not related to any previous request, meaning the server does not retain any information about previous requests from the same client. Client...

  In the world of APIs, there are many different architectural styles for building APIs, and each one has its own benefits, cons, and ideal use cases, but two prominent approaches dominate the landscape: gRPC and REST. Both have their unique strengths and weaknesses, making them suitable for different scenarios. In this blog, we’ll delve into the key differences between gRPC and REST, explore their use cases, and help you decide which one might be the best fit for your project. What is REST? REST or Representational State Transfer is an architectural style for designing networked applications. It relies on a stateless, client-server, cacheable communications protocol – the HTTP. RESTful applications use HTTP requests to perform CRUD (Create, Read, Update, Delete) operations on resources represented in a JSON format. What are advantages of using REST ? REST has several advantages that make it a popular choice for designing APIs. Here are the key benefits : - Simplicity : They are...

  When working with JavaScript, you often deal with objects. Objects are collections of key-value pairs, where each key is a unique identifier for its corresponding value. Checking if a kеy еxists in a JavaScript objеct is a common task for developers when working with JS objects. What are JavaScript Objects? JavaScript objects are fundamental to the language and are used to store data in a structured way. Each property of an object consists of a key and its associated value. Here’s a simple example of an object: javascriptCopy codelet person = { name: 'John', age: 30, city: 'New York' }; In this person object, name , age , and city are keys, and 'John' , 30 , and 'New York' are their respective values. How to check for Key in Object? Method 1: Using the in Operator The in operator is straightforward and allows you to check if a property exists in an object. Here’s how you can use it: javascriptCopy codelet person = { name: 'John...

  In today's digital world, applications need to communicate with each other to provide users with seamless experiences. This communication is often made possible through APIs (Application Programming Interfaces). API integration is a process where different software systems are connected using APIs, allowing them to share data and functionalities. Let's delve deeper into what API integration is, how it works, and why it's crucial for modern software development. What is an API Integration? API integration is the process of connecting two or more applications using APIs. This connection allows the applications to exchange data and perform functions cohesively. For instance, an e-commerce website might integrate with a payment gateway API to process transactions. You can think of an API has a set of rules and protocols that allows one software application to interact with another. It defines the methods and data structures that developers can use to interact with the softwar...

 As a developer, you usually work with JSON data, and may need to JSON compare files. This might involve checking a list of products from the database against a previous version or comparing an updated user profile returned by your REST API with the original data sent to the server. In this article, we'll explore several methods and tools developers can use to compare two JSON files effectively. What is a JSON File? JSON is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is organized in key-value pairs and arrays, making it versatile for representing various types of data. Here's a simple example of a JSON object: { "name": "John Doe", "age": 30, "city": "New York" } JSON files can contain nested structures, arrays of objects, and other complex data types, making their comparison non-trivial when done manually. Comparing JSON Files When compar...

  JSON or JavaScript Object Notation is a popular data interchange format used by developers to store and exchange data. It's lightweight, easy to read, and easy to parse, making it ideal for various applications. However, one of the notable limitations of JSON is that it doesn't support comments natively. This can be a problem when you want to include explanations, notes, or any sort of annotation within your JSON files. In this article, we'll explore some practical workarounds to add comments to a JSON file without breaking its structure or causing issues during parsing. Understanding JSON and Its Limitations JSON is designed to be a minimal and straightforward way to represent structured data. Its simplicity is one of its strengths, but it also means there are some limitations. Unlike other data formats such as XML or YAML, JSON does not support comments. This is because JSON is primarily intended to be a data format, not a document format. The official JSON specificatio...

  Introduction As software developers, we all write lots and lots of lines of code while building an application. But to ensure that each and every components work perfectly in the software, we really need to do some unit testing. This ensures proper functionality and reliable performance of our product. These testing of individual components is known as Unit Testing. For the dynamic nature and the ease of writing tests alongside the code, Python can be a viable option for unit testing of our software. So, let's dive into the nitty-gritty of writing unit tests and explore the best practices and techniques to ensure our code's reliability and maintainability. Why software needs to be unit tested? Often it's found that during the early development phase, unit tests serve as a safety net by helping us catching bugs and regressions. By verifying the behavior of individual units, one can always able to identify and fix issues before they propagate throughout the codebase. Also, ...
