Brace Completion and Auto Indentation in VS
When I started coding Node.js in Visual Studio 2015, I noticed that I didn’t get automatic brace completion anymore (e.g. matching of curly braces). When I installed Visual Studio 2017 and started coding JavaScript and TypeScript, I noticed the same thing. When you’re coding C# in Visual Studio, the IDE usually matches braces automatically, and when you press enter it’ll also automatically indent the new line with spaces or tabs, which wasn’t activated either.
Luckily it’s easy to activate these things for JavaScript and/or TypeScript, and while the screenshots below are from Visual Studio 2017, I think it looks pretty much the same in Visual Studio 2015 as well.
