Javascript C# like function expression

Question

I was testing some javascript functions in the Chrome console and found that I can write functions like C# expressions.

var testFunction = (v1, v2) => v1 + v2;
var result = testFunction(2, 3);
// result is 5

I have search about it on google, but I didn't find anything about this specific syntax.

Is this something new or just a resource from the Chrome console? Does browsers commonly support this?

Those are called Arrow functions and are supported in all browsers except IE and Opera Mini, as you can see in this Can I use link.

Thanks for the help. I know what it is about now. I looked the link you mention and search about the compatibility. I also made some tests and find that the current version of Opera Mini (and Opera Browser) does support it. I will look to use it in my javascript library for web systems, since Chrome support is fully supported. – Thiago Romam Jun 01 '17 at 14:58
