Arrow functions are introduced on ES6 the following is an example of arrow functions

var value = (x) =>{ console.log(x)}
value(12);
A working fiddle is attached
Arrow functions – also called “fat arrow” functions, from CoffeeScript (a transcompiled language) — are a more concise syntax for writing function expressions. They utilize a new token, =>, that looks like a fat arrow. Arrow functions are anonymous and change the way this binds in functions.

Arrow functions don't have the local variable arguments as do other functions. The arguments object is an array-like object that allows developers to dynamically discover and access a function's arguments. This is helpful because JavaScript functions can take an unlimited number of arguments.
In its most basic form, a function expression produces a value, while a function statement performs an action. With the arrow function, it is important to remember that statements need to have curly braces. Once the curly braces are present, you always need to write return as well.
