Typescript Function Declaration, style difference

Question

I started to use Typescript and i don't get what differences in these method declarations are:

onSave(){ /*method body*/ }
public onSave = () => { /*method body*/ }

Also, What I am supposed to search on Google or StackOverflow to find more about this topic?

Thank you,

(Sorry for the long post :D)

You are referring to regular functions and arrow function, they're explained in detail in TypeScript docs: http://www.typescriptlang.org/docs/handbook/functions.html

The general difference between a regular function and arrow function is that regular function operates within it's own scope (this) while arrow function remains in the scope of the parent.

Sorry but this is not quite correct. The question asks about method syntax vs property syntax. – Aluan Haddad Apr 04 '18 at 21:18
And what exactly is not correct in my answer ? Also I am pretty sure he's asking about the difference in function declaration ... – anteAdamovic Apr 04 '18 at 21:47

The link you passed in the comment has exactly the same answer as mine ... you failed to make your point. – anteAdamovic Apr 05 '18 at 06:48
Thank you mate. I was asking about function declaration as well @AluanHaddad. – Im Flash Apr 05 '18 at 10:15
@AnteJablanAdamović you're right, I overlooked that. Sorry: +1 – Aluan Haddad Apr 06 '18 at 06:29
