Previously, I learned lambda as shorten way to make instance of function(I learned from C# book), but when I used lambda with Vue.js, I encountered a problem. This works well:

mounted: function(){ (...)

But this not works:

mounted: () => { (...) }

I want to get perfect explanation for this.

  • The context of `this` is saved using arrow functions. I wouldn't be surprised that the this context is wrong at time of declaration, but having only 1 function it's hard to say – Icepickle Nov 06 '17 at 08:17

    Don't try to infer anything from C# to JS. Despite the syntactic similarity to lambdas, arrow functions are just one syntax amongst many for creating inline functions in JS. – Bergi Nov 06 '17 at 08:26
