array.includes()

[MarioDings]

Just got a message: Unhandled exception: TypeError: Expected a function.

on: if ( !bestandenlijst.includes(file) ) doThis();

file="2.png"

bestandenlijst = ["1.png","2.png", "3.png","4.png","5.png"]

Doesnt fitbit understand the function includes()

Hi @MarioDings 

Are you developing an application using the Fitbit Web API or Fitbit Device SDK?

Gordon, 

I use the Fitbit Device SDK (Studio)

I'm autodidact, so I try everything I find in a diversity of courses.

Also tried console.table(..) but that is not documented, so no problem.

Thank you for clarifying.    I'm moving this post to the SDK community.   Someone there should be able to help you.

Fitbit only supports everything in ES5.1, with some extensions. I think .includes() may have been introduced into JS after ES5.1.
