Demo code for Vanilla JS fails with "e.on is not a function"

[pguillem]

I copied and pasted the VanillaJS code to a test.html. Opened on chrome but the site stays blank, and returns the following error:

statSeqs.js:66 Uncaught TypeError: e.on is not a function
    at Us.resetSeqs (statSeqs.js:66:10)
    at new e (statSeqs.js:22:8)
    at e (statSeqs.js:14:12)
    at OverviewBar.js:78:21
    at index.js:70:25
    at index.js:30:25
    at index.js:84:33
    at t.<anonymous> (index.js:30:25)
    at index.js:80:37
    at t.bar (index.js:30:25)

Looks like some buggy line on the node module reselect/es/index.js Any ideas?

Thanks in advance! Pedro
