  In today’s microservices and distributed architectures, understanding terms like reverse proxy, API gateway, and load balancer is essential. Although these components might seem similar, they each serve a distinct purpose in managing, routing, and securing traffic between clients and servers. In this blog, we’ll break down each one, look at how they work, and provide examples with Node.js code to demonstrate their usage in real-world scenarios. What is a Reverse Proxy? A  reverse proxy  is a server that sits between client requests and backend servers, forwarding client requests to backend services. It’s responsible for hiding internal server details, distributing load, and enhancing security. Key Features of a Reverse Proxy: Hides backend server details, improving security. Routes requests to different servers based on conditions. Caches content to improve performance. Example Scenario with Code Suppose we have a backend with two microservices: Service A  running ...

  In JavaScript, comparing values is a frequent operation, and understanding the difference between  ==  (loose equality) and  ===  (strict equality) is crucial to  avoid unexpected behavior   in your code. While both operators are used for comparisons, they handle type-checking differently, which impacts performance and functionality. Let’s dive into how each works, their internal mechanisms, and when to use each to ensure your code remains clean and bug-free. ==  (Loose Equality) The  ==  operator is known as  loose equality  because it checks only if the values on both sides are “loosely equal.” When you use  == , JavaScript will try to  coerce  (or convert) the data types of the two values to make them compatible before comparing them. If the values are not the same type, JavaScript attempts to convert one or both values so that the comparison can proceed. How  ==  Works The internal mechanism of...
