Polymer is a JavaScript library that helps you create custom reusable HTML elements, and use them to build performant, maintainable apps. 

Polymer is a lightweight library that helps you take full advantage of Web Components.

With Web Components, you can create reusable custom elements that interoperate seamlessly with the browser’s built-in elements, or break your app up into right-sized components, making your code cleaner and less expensive to maintain.

In fact, Polymer's task is not only to simplify the creation of sites, Polymer should help create web applications that can function without additional interference on various devices: from desktops and mobile platforms to TVs. Polymer can be called the embodiment of Material Design for the web.

Polymer went from an experiment to a Big Thing serving tons of users in major Google products and some of the biggest companies in the world in no time. Success is great! But there’s always room for improvement. Mistakes were made. Lessons were learned. Regrets were had. Two years, hundreds of elements, and thousands of apps later, we’ve got a pretty good idea what makes an element and an app great, and what’s changing in Polymer 2.0 as a result.

Microsoft has released the development environment Visual Studio Code 1.30. The tool has received new features, as well as improved support for JavaScript and TypeScript.

The search tool in the new version of the editor allows you to make multi-line queries. You can add a new line to the query by pressing Shift + Enter or simply by pasting text from the clipboard.

Custom headers and menu items in Linux are now activated by default. Since some menus may go beyond the boundaries of the screen, the developers added the ability to scroll.

Menu items designed to work with the settings have been moved to the title bar of the editor.

In the snippet, new comment variables are implemented, allowing to leave lines or blocks of notes based on the language of the code.

Also, the developers added the Go to Declaration and Peek Declaration commands to Visual Studio Code 1.30 in addition to the existing Go to Definition and Peek Definition. This is due to the fact that in some languages ​​the concepts of definition and declaration are fundamentally different.

In Visual Studio Code 1.30, you can work with TypeScript 3.2.2. Display of callbacks in JavaScript and TypeScript is improved. The new version of the editor displays which function they belong to.

The developers have improved the integration with the repository. In the new version of the program, you can change the tool that opens the file by clicking on the version control panel.

The Visual Studio Code 1.30 error detection and removal tool allows you to delete debug consoles for inactive sessions. Improved concept of variable substitution in launch.json configuration. The initial debug configuration itself has been simplified by hiding minor elements and adding a Quick Pick interface.

You can set the task to run automatically when you open the project folder. In addition, several new tasks have been added to the task management command section, for example, Tasks: Rerun Last Task, which allows you to restart the previous process.
