An arrow function expression is an anonymous function expression written with the "fat arrow" syntax ( = ). Like traditional function expressions, arrow functions are not hoisted, and so you cannot call them before you declare them. They are also always anonymous-there is no way to name an arrow function.



Unlike regular functions, arrow functions do not have their own this . The value of this inside an arrow function remains the same throughout the lifecycle of the function and is always bound to the value of this in the closest non-arrow parent function.




An arrow function doesn't have its own this value and the arguments object. Therefore, you should not use it as an event handler, a method of an object literal, a prototype method, or when you have a function that uses the arguments object.



Arrow functions are an ECMAScript2015 syntax for writing anonymous functions. They have a lot of features that separate them from the original function keyword in JavaScript, but in many cases they can be a drop-in replacement for anonymous functions.
