It’s clear we are undergoing a Digital Transformation Era. Companies across all sectors have placed significant investment on their own digital platforms: e-banking, e-commerce, PWA’s, streaming services, and much more.Achieving differentiation in this Era means pushing software development teams to deliver highly advanced applications in record time. Developing every single feature in-house has long stopped being sustainable. Now, developing digital products means re-using third-party code and integrating third-party scripts for added functionality.Code Dependencies and Third-Party ScriptsThe growth of JavaScript as the language of the Web has led to the emergence of libraries and frameworks — two major promoters of development speed.If we look at a typical development scenario for (...)

Learn how OpenAPI 2.0 and 3.0 can promote and emphasis #api Security as a first-class concern during the design phase of API development.It is no longer a mystery, APIs are eating the world. There are a lot of companies today that are offering their APIs as the primary medium to interact with a system, with the User Interface merely as a byproduct, or, in any case, not the primary product being sold. Companies such as Stripe and Twilio led the vanguard of this movement in 2012.Given this shift (which, by the way, is still happening), APIs have started to get more and more complicated, and so the API development process needed to evolve as well. APIs have become a product, therefore all the typical team members and methodologies have been employed to make that product successful.The (...)

Quicksort is one of the most efficient methods for sorting an array in computer science. For a thorough breakdown, it has its own Wikipedia article.This article will cover implementing quicksort in JavaScript. Quicksort is not built in to JavaScript. Due to the sort method on the Array prototype, sorting is rarely questioned or optimized in the language. Despite that, Quicksort is still an important algorithm to at least comprehend, whether or not you use it.How does it work? 🤔Quicksort works by picking an element from the array and denoting it as the “pivot.” All other elements in the array are split into two categories — they are either less than or greater than this pivot element.Each of the two resulting arrays (array of values less-than-the-pivot and array of values (...)

From #wordpress to JAMstack : How to make your website 10x faster
▻https://hackernoon.com/from-wordpress-to-jamstack-how-to-make-your-website-10x-faster-e363abc46

Performance matters. If you are familiar with JAMstack, the movement encourages avoiding server-side rendering completely in favor of pre-build, purely static HTML pages. By serving only JavaScript, APIs, and Markdown (JAM) over a CDN, a website’s performance is dramatically increased, making for a much better user experience.If you have an existing WordPress website, you may be familiar with slow page load. This can be due to server-side processes that occur prior to even getting to the HTML. If you are looking to make the switch to a better experience for your users, it might be time to switch to a JAMstack website. And making the switch may be easier than you think.In this tutorial we’re going to import existing WordPress content into a JAMstack website, deploy to Netlify, then (...)

When your React application reaches a certain size and scope, attempting to manage state within component instances adds too much complexity, prop drilling, and code smell. Developers inevitably turn to global state management tools, such as MobX or #redux, to solve these problems and make their lives simpler. I strongly endorse Redux and use it in my personal projects, but not all developers share my sentiment.I have worked on quite a few large projects that have demanded a global state powerhouse behind the React UI. No matter application size, team size, or member seniority, the almost universal opinion of these global state management packages has been overwhelmingly negative.The top two complaints? Boilerplate and learning curve. While these packages solve a lot of problems and (...)
