Any software development project will almost certainly have through several tests by the time it is finished, especially in an Agile testing environment where testing and development occur simultaneously. But, no matter how many tests you've conducted, there's really only one way to tell if your software can handle the actual demands your army of end-users will be throwing on it once it's nearly finished. It's known as load testing.

You may have come across the word "nameserver" if you maintain your own website. You may, however, have no true idea of what one is or how it works. Knowing a little about the “nameserver” concept can help you manage your website. Simply said, nameservers help browsers in establishing links between URLs and websites. They're essential since we'd have to memorize IP addresses to visit websites if we didn't have them.

Do you frequently find yourself typing a long command on the command line or checking the bash history for a command you've already typed? If you answered yes to any of the above questions, bash aliases will come in helpful. You can use aliases in Bash to create a shortcut command for a longer command. When working on the command line, bash aliases are essentially shortcuts that can save you time and effort by eliminating the need to remember long commands.

During the execution of a PHP application, it is possible for it to generate a wide range of warnings and errors. For developers seeking to troubleshoot a misbehaving application, being able to observe these errors is critical. Developers, on the other hand, frequently encounter difficulties when attempting to display errors from their PHP applications. Instead, their applications simply stop working.

Logging helps developers in reducing errors and cyber-attacks. The application is designed to be dynamic. We can't always predict how an application will react to data changes, errors, or program changes. Logging in allows us to better understand our own programs. For all applications, an absolute logging solution is essential. A good logging system increases the application's stability and makes it easier to maintain on the production server.

In recent days web application has become a vital part of our day-to-day life. We often don’t understand the technology behind an application as how it works, what type of programming languages have been used or what kind of databases are used to store and retrieve data. But when you try to create one such application you should definitely know how to build an application and the technology stack behind it.

In the past few years, JavaScript has evolved in several ways and has come a long way. With the evolving technology, machines are becoming more powerful, and browsers are getting more robust and compatible. In addition, Node.js’s recent development for JavaScript’s execution on servers, JavaScript has been getting more and more popular than ever before.

whenever we go to a website, whether it's an online store to buy clothes or to check the status of our bank account, we need to type the URL into the browser. When you click on the relevant page, a request is sent to the server, and the server always responds with the HTTP three-digit code. This HTTP status code tells us if our request was successfully completed or whether there was an error that prevented the server from serving the content that users or visitors were trying to access.

No one is perfect in this world including machines. None of our days pass without having errors faced in our professional life. Whenever we are facing any issues/errors while working rather than worrying, let us all fix our mind like we are going to learn something new. This will make your tasks easier. One of our friend Error Handling will help us in fighting with these errors. These reduce our pressure by finding the errors and guide us to achieve the desired output.

One of the most typical things a developer does is make an HTTP call to an API. An API request can be sent in a variety of ways. We can use a command-line tool like cURL, the browser's native Fetch API, or a package like Axios to accomplish this. Sending HTTP requests to your API with Axios is a fantastic tool. Axios is supported by all major browsers. The package can be used for your backend server, loaded via a CDN, or required in your frontend application.
