I know Google Trends are not much relevant, but it can be a good parameter of global interest. Node.js and .NET Core are two hot topics among developers these days. Node.js was released in 2009, and Microsoft introduced .NET Core in 2016, almost seven years later.

Node.js is backed by huge open-source communities of JavaScript and TypeScript. Microsoft adopted this culture just a couple of years ago and has gradually become one of the open-source leaders. MS has developed some amazing things recently, and .NET Core is one of them.

Developers love .NET Core very much. Being the true successor of .NET, only at the age of three, it already offers a rich ecosystem. .NET Core has surpassed Node.js in the search term, and its web framework ASP.NET Core will soon do the same. It is very satisfying to see an amazing technology like .NET Core is getting some traction, cheers!
