button elements offer attributes to change form behavior

By default, the button within the form element sends a POST request to the form’s action URL with application/x-www-form-urlencoded encoded data as long as the inputs values are valid. However, it looks like we can override this functionality using formaction, formenctype, formmethod and formnovalidate attributes. Stefan Judis explains it well in this article.

Fleet - Next-generation IDE by JetBrains

A quick and lightweight text editor with IDE features built by JetBrains is coming. It looks like distributed deployment and collaboration tools are coming built-in. The design also looks top notch. It has a built-in terminal, git support, debugger, theming support, plugins, and all the things you would expect from an app like this in 2022. I am very interested in this one, and I am glad that some real competitor for Visual Studio Code is coming.
