Crashes UglifyJS

We’re using the latest package in a project and during the uglify build step, UglifyJS crashes because of index.js. Seems that built index.js still has let instead of var.

Specifically this line in index.js is causing the error:

    let tokens = state.tokens;

@zmiKaminski You can use the browser build like this:

var attrs = require('markdown-it-attrs/markdown-it-attrs.browser.js')

The browser build does not contain any ES2015.

@zentuit I am experiencing this same error as you but with markdown-it-attrs 1.0.1 & 1.1.0 using uglify-js 3.1.0. Perhaps you can tell me what version combination is working for you?
