Kotlin has gradually replaced Java as the lingua franca of Android programming. It’s a more concise language than Java, meaning your code works harder and you can build leaner applications. And Kotlin Collections are fundamental. These collections play a fundamental role in our work as programmers by simplifying the organization and management of data. Whether it’s a list, set, map or other data structure, they allow us to categorize and store data logically.

In the 21st century, practically all technological innovation on the planet has been channeled into the mobile phone. The first generation of mobile phones simply allowed you to make calls, store numbers and play rudimentary games (some of which, like Snake, didn’t even have an end sequence because the designers didn’t think anyone would complete them). Today mobile phones are computers in our pocket, allowing us to shop, date, stream videos, buy food, order cabs and find our way around.

The software industry has evolved more quickly in 10 years than most industries do in 1,000, yet we continue to grapple with the basic elements of date and time. Practically all our apps rely on time in some way, and when our users are spread all over the world it can be fiendishly difficult to get the timestamps right. Kotlin language, the dominant Android programming language, provides native classes (or blueprints) to help us deal with date and time.

Android has surged past iOS to dominate the world’s smartphone market, but its ecosystem is growing at an exponential rate. There were more than 24,000 different Android devices at the last count, which places major strains on devs. To learn Android development, you have to learn how to optimize for hundreds of different devices. So you need a clear learning plan that can be applied to the entire Android ecosystem.

There are now nearly 9 million apps worldwide, and practically all of them run on an internal clock. Financial apps are built on timestamped data. Office apps run on calendars. Social apps are defined by their feeds, timelines and anniversaries. So, as devs, we need to know how to compute date and time. JavaScript, the world’s most popular programming language, has plenty of helpful APIs, but they can throw up complications if you’ve never used them before.

Developers striving to learn iOS face a rate of change that’s unprecedented in mobile history. iOS 17 is about to go live, just weeks after Apple released the latest versions of iOS 15 and 16. The latest upgrade will cut off all versions up to the iPhone X (which itself is only six years old) and comes with: If you really want to learn and master iOS app development, you need a blend of learning resources that cover all these topics, as well as all the basics of iOS.

Application Programming Interface, or API, development is a critical aspect of modern software engineering, enabling diverse software systems to interact and share data seamlessly. The API serves as a contract between different software applications, outlining how they can communicate with one another. Two of the most popular architectural styles for building Web APIs are Representational State Transfer (REST) and GraphQL.

Not even Tim Berners-Lee, the inventor of the world wide web, could have predicted the pace or breadth of its expansion over the last 30 years. Once, the web was only accessible via clunky desktop computers: today, it can also be reached from laptops, tablets, mobile phones and even smartwatches. What’s more, consumers want native apps that are unique to a particular platform and they expect updates to be provided seamlessly.

“A single-threaded, non-blocking, asynchronous, concurrent programming language with many flexibilities”. This is how freeCodeCamp defines JavaScript. Sounds great, right? Well, read it again. JavaScript is supposed to be single-threaded and asynchronous simultaneously. Which, when you think about it, sounds like a contradiction.

Data is essential to all JavaScript applications. It determine what we see, hear and interact with when we open the app, and it must be stored properly to guarantee a smooth user experience. Specifically, the data must be a stored in a way that facilitates retrieval, manipulation and is efficient in storage usage. need data to represent information. One of the most important prominent data structures in JavaScript is known as an Array.
