Arrow function was introduced in ECMA 6.  It is different than function statement or expression , as it does not have its own ‘this’ , and can also not be used as constructor.  Some important points about Arrow function are:

• It does not have prototype property
• It does not have arguments parameter
• It does not have its own ‘this’
• It can not be used with new operator

I have written a detailed article on Arrow function here :
