Few lines of code, no matter how great your development team is, run at peak performance when they're originally developed. To discover the most effective technique to make code run quicker, it must be evaluated, debugged, and reviewed. How can software engineers and quality assurance engineers ensure that their code is fast, efficient, and ultimately valuable? The approach is to evaluate an application's code and discover and resolve performance bottlenecks using code profiling.

For any developer, console.log() is one of the most well-known javascript functions since it allows us to quickly check for errors in our code in some circumstances. If you're unfamiliar with it, it's a tool that Javascript developers use to debug their code. Almost all popular browsers include a console, which comes in helpful for debugging Javascript. To access your browser's console, you use the console object of Javascript.

Since the turn of the century, websites have progressed dramatically. What used to be a network of basic text-based pages has developed into a network of carefully created experiences, complete with responsive buttons, parallax scrolling, and tailored information. These website design aspects don't appear out of anywhere, of course.

Node.js is a free, cross-platform JavaScript runtime environment, while single-threaded in nature, executes asynchronous code using several threads in the background. Because of its design, Node.js has received a lot of flak. It seems unusual that Node.js doesn't have direct access to threads when compared to programming languages like Java, C, or Python. The worker_thread module in Node.js 11 allows us to launch many threads on a single core.

WordPress is the most popular blogging platform in the world. In addition to the popularity of WordPress as a blogging platform, it is also used by a variety of other websites for a myriad of different purposes. From small businesses to large media sites, WordPress is a platform that offers a lot of potential for a wide range of different websites.

The performance of a applications and company's infrastructure is critical to its success. We all know how crucial logs are when it comes to diagnosing performance and availability issues. Is troubleshooting, however, the sole function of logs? Obviously not. You've probably discovered they're vital in other ways as well throughout the years. The visualisation of business dashboards is another use of logs. Here's why JSON logging is the ideal format for storing logs.

One of the most popular Node.js web frameworks is Express.js. It enables you to rapidly and easily create APIs and other web applications. However, constructing a server is only half the battle; the other half is keeping it running. You should read the logs to have a solid grasp of what's going on with your application.

Although the RESTful Application Programming Interface (API) was first established in the year 2000, there are currently no set guidelines or standards for API development. Developers have experimented with many methods to improve REST API solutions throughout the years. Some of them were successful, while others were unsuccessful. APIs that are poorly developed is difficult to maintain over time and are prone to failure.

Over the course of two decades, a lot of data has been made available online in order to fully realise PHP's potential. It is one of the most widely used programming languages, and some consider it to be one of the easiest to learn. Even the most advanced languages require some assistance. Many PHP tools available in its vast ecosystem can be of assistance. The most valuable tool is a PHP profiler. In general, profilers are beneficial to all levels of developers.

Many current web applications rely on near-frictionless and simultaneous access to numerous API providers' Web APIs. However, the web's default is to prohibit such "loose" behaviour, much like a firewall that blocks access to untrusted parties in the name of security. That default, thankfully, can be safely altered. Before doing so, however, it is necessary for both Web application developers and API providers to understand the concepts of Cross-Origin Resource Sharing (CORS).
