Introduction. Today, the demand for software is higher than ever. Lines of code govern almost everything we do in our day-to-day activities. The way we buy, the way we sell, even the way we communicate. In 2019, according to Evans Data Corporation, there were 23.9 million developers worldwide. In an attempt to hold their place within the market, developers are having to speed their process up whilst delivering products of ever-increasing quality.

Our top design priorities at the time were security, elasticity, reliability, durability, performance and cost because that’s what customers told us was most important to them for these types of applicat

Three facts. Apple bars web apps from the only App Store allowed on iOS. [1]. Apple forces developers of competing browsers to use their engine for all browsers on iOS , restricting their ability to deliver a better version of the web platform. Apple claims that browsers on iOS are platforms sufficient to support developers who object to the App Store's terms.and a proposition: Apple's iOS browser (Safari) and engine (WebKit) are uniquely under-powered.

From time to time, I think I mainly adopted a more concise way of writing code.

There is no doubt that CSS plays a huge role in web performance. Milica Mihajlija puts a point on exactly why: When there is CSS available for a page, whether it’s inline or an external stylesheet, the browser delays rendering until the CSS is parsed. This is because pages without CSS are often unusable. The browser has to wait until the CSS is both downloaded and parsed to show us that first rendering of the page, otherwise browsing the web would be a terribly visually jerky to browse.
