28,149 PointsAre you using babel? If you're trying to do this in a browser, they they can't understand (e) =>, however if you're using babel, it will compile ES2015 into browser-compatible JS (i.e. it'll spit out function(e)) which the browsers can read.

231,248 PointsArrow functions can't always be substituted for conventional functions. For example, they can't be used as constructors, and they don't provide several of the bindings conventional functions do (most notably "this").
For more details see this MDN page on Arrow Functions.
If that's not the issue, please show more of your code or make a snapshot of your workspace and post the link to it here.
