ES5 or ES6+ input?

Uglify version (uglifyjs -V)

JavaScript input

The uglifyjs CLI command executed or minify() options used.

JavaScript output or error produced.

I'm trying to serialize function in documentation.
I have a function

  const handler = (props, next) => (count) => {
    if (Math.random() < possibility) {
      next();
      log('hit', possibility, props, count);
    } else {
      log('miss', possibility, props, count);
    }
  };

And I used handler.toString() to print it out:

It's pretty good. But after uglify:

So I'm thinking If I can have some thing like the /* disable-eslint */, /* disable-enable */, /* disable-enable-line */, /* disable-enable-next-line */ in eslint library.
So I can write the code like this:

/* uglify-compress-disable */
  const handler = (props, next) => (count) => {
    if (Math.random() < possibility) {
      next();
      log('hit', possibility, props, count);
    } else {
      log('miss', possibility, props, count);
    }
  };
/* uglify-compress-enable */

In your particular example, disabling reduce_vars may make your customised requirements work.
