The post Converting an Array to JSON Object in JavaScript first appeared on Qvault . JSON, or “JavaScript Object Notation”, is one of the most popular data exchange formats, particularly in web development. If you have an array of data but the program you’re communicating with requires an object, don’t fear, we’ll go over some easy conversion methods. Quick Answer – JS Array to JSON Arrays are actually valid JSON, so if you just need to prepare your array in order to make a fetch request with it, it’s as easy as using the JSON.stringify() method. const resp = await fetch('https://example.com', { method: 'POST', mode: 'cors', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify([1, 2, 3, 4, 5]) }); The  JSON.stringify()  method converts a JavaScript object, array or value to a JSON string that can be sent over the wire using the Fetch API (or another communication library). Weird Answer – Arra

The post Should you Learn Computer Science or Software Engineering? first appeared on Qvault . The most important thing to understand about these two fields of study is that, ultimately, they are similar. At the end of the day, Software Engineering and Computer Science will both help to make you a better programmer and developer, and the only difference between the two is how they are applied. Software Engineering tends to be more practical, and Computer Science tends to be more theoretical. In a way, Software Engineering is just applied Computer Science, and using that as a starting point, we can examine the differences between the two. The Differences Software Engineering is the study of how software systems are built. While studying and practicing Software Engineering, there is a distinct focus on the following topics: Application development Project management Quality assurance Software testing and maintenance Clean code and clean architecture Security Continuous integ

The post The Best Guide to Getting a Certificate in Computer Science in 2021 first appeared on Qvault . There are so many reasons to want to get a certificate in computer science in 2021, especially when you compare it to alternatives like getting a degree or attending a coding bootcamp. While computer science certificates take time and sometimes money to complete, they still accomplish the same aim as degrees and bootcamps: to show future employers that you have the skills and understanding required to get the programming job of your dreams, and you can get one in a heck of a lot less time and money than a degree. Sometimes certificates in computer science are a prerequisite for the job you want, but oftentimes, they’re just a handy way to prove your chops. This article will guide you through the six steps you’ll need to find the right certificate in computer science for you, complete it, and leverage it to get your dream job in computer science.  There’s no right answer, so thi

The post 6 Computer Science Resume Examples for 2021 first appeared on Qvault . It’s really hard to get your foot in the door for engineering interviews, especially if you have no experience and are looking for an entry-level position. Often times, more experienced candidates looking to find a higher-paying job can also have trouble. As an employer myself, I can tell you that one of the biggest mistakes I see in 75% of resumes is using a visually boring template . When I’m sifting through forty or fifty applicants, it’s really easy for my eyes to glaze over. Think of your resume as your website landing page. You need to catch your employer’s attention by calling out your biggest accomplishments and selling points at a glance. I’ve looked at hundreds of resumes from computer science students, researched other’s opinions about what works and what doesn’t, and compiled a list of the top 6 resume templates that will help you get your point across no matter your work experience, desire

The post What’s the Job Outlook for Computer Science Students? first appeared on Qvault . As the world becomes more and more dependent on technology, the demand for computer skills has increased immensely as well. The opportunities in information technology across all industries have never been greater, as worldwide ICT spending is expected to reach $4.3 trillion this year . In response, the sector has grown considerably into specialized fields, and computer science programs have pushed the envelope of how we train and prepare the next generation of technology experts. All in all, the world of computer science is getting bigger. And there is no better time to consider taking the path of computer science than now. Job Prospects and Salary Expectations Computer science graduates, especially those with high GPAs, are usually expected to land jobs with the highest salaries, with many employers paying well above expected salary grades. Many land jobs with starting salaries in the hig

The post The History of Computer Science – A Timeline first appeared on Qvault . Prehistory The Antikthyera Mechanism For as long as humans have needed to count, they have endeavored to find ways to make that process simpler. The abacus, first invented in Sumer sometime between 2700 and 2300 BCE, was more a rudimentary counting assistant than an actual computer. It did, however, represent the first stride humans took towards using tools to assist with mathematics. Much later, around 100 BC, the Antikythera Mechanism would be used to calculate astrological positions, for the purpose of sea travel. Unlike the abacus, it is likely that the mechanism was, in fact, the earliest form of an analog computer. As time went on, analog machines such as this would be used to keep track of the stars, and eventually, to keep track of time. Industrial Revolution Like many things, the Industrial Revolution proved necessary to catalyze an iteration of the lessons of Computer Science and tra

The post Should you Learn Computer Information Systems or Computer Science? first appeared on Qvault . As technology continues to advance, the need for professionals who are capable of utilizing and understanding computers continues to grow. This demand creates a strong job market, with excellent pay and exclusive opportunities. However, there are two fields of study when it comes to working with this technology: Computer Information Systems and Computer Science . Both are useful areas of study with in-demand skills, but what are the benefits of each, in comparison to each other? We explore that below. What are Computer Information Systems? Computer Information Systems are essentially in charge of coordinating the practical application of technology within any commercial setting, also known as Information Technology (IT). Whether or not a business has a dedicated IT professional, it will undoubtedly make use of a wide variety of Information Systems. The larger the company, however

The post What’s the Difference Between a Certificate or a Diploma in Computer Science in 2021? first appeared on Qvault . When I was looking into getting my first job related to programming, I had no idea what the difference between a certificate or a diploma was. I was terrified that I’d have to go back to school and spend 2-4 years getting a degree in computer science before an employer would even blink in my direction. Unfortunately for me, two degrees in conservation biology aren’t really enough to attract any serious coding employers. Then I learned about boot camps, which eased my concerns some, but I didn’t have time or money to spend on a 15-week program.  The thing that ended up helping me get my first programming job was actually an online certificate I got after completing an intro to SQL course – and of course the relevant knowledge that came with my certificate. If you want to get a programming job or a coding job, you probably already know that your employers want to
