Kotlin 1.4 now available with quality and performance improvements

JetBrains has released the latest version of Kotlin. For Kotlin 1.4, the team focused on quality and performance of the language and its tooling. This release includes over 60 performance fixes.

One performance enhancement is that files open much faster and content is highlighted faster. According to the team, content will appear highlighted 1.5 to 4 times faster than before. The team also improved the speed at which autocomplete suggestions appear. 

The IDE also got a few new updates, including a new feature called Coroutine Debugger, which allows developers to pinpoint bugs in concurrent applications, and a new Kotlin Project Wizard for creating and configuring Kotlin projects. 

There is also a new compiler that enhances Kotlin’s performance and extensibility. According to JetBrains, the main goals in developing this compiler were that it be fast, unify the platforms Kotlin supports, and provide an API for compiler extensions. 

Kotlin 1.4 also adds a number of library improvements, including:

  • SAM conversions for Kotlin interfaces
  • Explicit API mode for library authors
  • Mixing named and positional arguments
  • Trailing comma
  • Callable reference improvements
  • Using ‘break’ and ‘continue’ inside ‘when’ in loops 

More information about the new release is available here. 

JetBrains is also hosting a four day online event for Kotlin 1.4, which will feature talks and Q&As with the Kotlin team.

Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
